There are 3 green balls,5 red balls and 2 yellow balls in a bag.You take out one without looking.What is the probability of picking out a yellow ball?
To find the probability of picking out a yellow ball, we need to determine the total number of balls and the number of yellow balls in the bag.
Total number of balls = 3 (green) + 5 (red) + 2 (yellow) = 10 balls
Number of yellow balls = 2
So, the probability of picking out a yellow ball can be calculated as:
Probability = Number of yellow balls / Total number of balls = 2 / 10 = 1/5
Therefore, the probability of picking out a yellow ball is 1/5 or 0.2, which can also be expressed as 20%.
To find the probability of picking out a yellow ball, we need to know the total number of balls in the bag and the number of yellow balls in the bag.
In this case, there are a total of 3 green balls, 5 red balls, and 2 yellow balls, giving us a total of 10 balls in the bag.
The probability of picking out a yellow ball can be calculated by dividing the number of yellow balls by the total number of balls.
So, the probability of picking out a yellow ball is:
Number of yellow balls / Total number of balls
In this case, the number of yellow balls is 2 and the total number of balls is 10.
Therefore, the probability of picking out a yellow ball is 2/10, which can also be simplified as 1/5 or 0.2.
So, the probability of picking out a yellow ball is 0.2 or 20%.
two yellow and 10 total
2/10 = 0.2 or 1/5
