Question
A bag contains eleven balls labeled 1 through 11. One ball will be randomly picked. What is the probability of picking a multiple of 3? Write your answer as a fraction.2 points3/81/33/103/11
Solution
The multiples of 3 from 1 to 11 are 3, 6, and 9. So, there are 3 balls that are multiples of 3.
The total number of balls is 11.
The probability of an event is calculated by dividing the number of favorable outcomes by the total number of outcomes.
So, the probability of picking a ball that is a multiple of 3 is 3 (favorable outcomes) divided by 11 (total outcomes).
Therefore, the probability is 3/11.
