Annabelle owns a small business selling clothing. She knows that in the last week 56 customers paid cash, 26 customers used a debit card, and 9 customers used a credit card.
Based on these results, express the probability that the next customer will pay with a debit card as a percent to the nearest whole number.
First, calculate the total number of customers in the last week:
56 (cash) + 26 (debit card) + 9 (credit card) = 91 customers
Next, calculate the probability of the next customer paying with a debit card:
26 (debit card) / 91 (total customers) = 0.2857
Finally, convert the probability to a percentage:
0.2857 * 100 = 28.57%
So, the probability that the next customer will pay with a debit card is 29% to the nearest whole number.
In a popular online role playing game, players can create detailed designs for their character's "costumes," or appearance. Tariq sets up a website where players can buy and sell these costumes online. Information about the number of people who visited the website and the number of costumes purchased in a single day is listed below.
187 visitors purchased no costume.
228 visitors purchased exactly one costume.
29 visitors purchased more than one costume.
Based on these results, express the probability that the next person will purchase no more than one costume as a percent to the nearest whole number.
First, calculate the total number of visitors in a single day:
187 (no costume) + 228 (one costume) + 29 (more than one costume) = 444 visitors
Next, calculate the probability that the next person will purchase no more than one costume:
(187 (no costume) + 228 (one costume)) / 444 (total visitors) = 415 / 444 = 0.9337
Finally, convert the probability to a percentage:
0.9337 * 100 = 93.37%
So, the probability that the next person will purchase no more than one costume is 93% to the nearest whole number.
In a popular online role playing game, players can create detailed designs for their character's "costumes," or appearance. Jackson sets up a website where players can buy and sell these costumes online. Information about the number of people who visited the website and the number of costumes purchased in a single day is listed below.
159 visitors purchased no costume.
32 visitors purchased exactly one costume.
21 visitors purchased more than one costume.
Based on these results, express the probability that the next person will purchase no more than one costume as a percent to the nearest whole number.
First, calculate the total number of visitors in a single day:
159 (no costume) + 32 (one costume) + 21 (more than one costume) = 212 visitors
Next, calculate the probability that the next person will purchase no more than one costume:
(159 (no costume) + 32 (one costume)) / 212 (total visitors) = 191 / 212 ≈ 0.9005
Finally, convert the probability to a percentage:
0.9005 * 100 ≈ 90.05%
So, the probability that the next person will purchase no more than one costume is 90% to the nearest whole number.
Which event is most likely to occur?
Rolling a number greater than or equal to 3 on a eight-sided die, numbered from 1 to 8.
Spinning a spinner divided into five equal-sized sections colored red/green/yellow/blue/purple and landing on green or purple.
Winning a raffle that sold a total of 100 tickets, if you buy 0 tickets.
Reaching into a bag full of 78 strawberry chews and 2 cherry chews without looking and pulling out a strawberry chew.
In order to determine which event is most likely to occur, we need to assess the probability of each event happening.
1. Rolling a number greater than or equal to 3 on an eight-sided die:
- There are 6 numbers greater than or equal to 3 on an eight-sided die: 3, 4, 5, 6, 7, 8.
- Probability = Number of favorable outcomes / Total number of outcomes = 6/8 = 3/4 = 0.75
2. Spinning a spinner and landing on green or purple:
- There are 2 sections (green and purple) out of 5 total sections that are favorable outcomes.
- Probability = Number of favorable outcomes / Total number of outcomes = 2/5 = 0.4
3. Winning a raffle with 100 tickets if you buy 0 tickets:
- Probability = Number of your tickets / Total number of tickets sold = 0/100 = 0
4. Reaching into a bag and pulling out a strawberry chew:
- There are 78 strawberry chews out of a total of 80 candies (78 strawberries + 2 cherries).
- Probability = Number of favorable outcomes / Total number of outcomes = 78/80 = 39/40 = 0.975
Based on the calculations, the event with the highest probability of occurring is reaching into the bag full of strawberry chews and pulling out a strawberry chew with a probability of 0.975.
