45 customers paid cash, 10 customers used a debit card, and 64 customers used a credit card. Based on those results express the probability that the next customer will pay with a debit card as a decimal to the nearest hundredth
There were a total of 45 + 10 + 64 = 119 customers.
The probability of the next customer paying with a debit card is 10/119 ≈ 0.08 (rounded to the nearest hundredth). Answer: \boxed{0.08}.
To find the probability that the next customer will pay with a debit card as a decimal, we need to divide the number of customers who paid with a debit card by the total number of customers.
The total number of customers who paid with a debit card is 10.
The total number of customers is the sum of customers who paid with cash, debit card, and credit card, which is 45 + 10 + 64 = 119.
So, the probability of the next customer paying with a debit card is 10/119.
To express this as a decimal to the nearest hundredth, we divide 10 by 119: 10/119 ≈ 0.08.
Therefore, the probability that the next customer will pay with a debit card as a decimal to the nearest hundredth is 0.08.
