| 1) First, find the total number of outcomes.
5 + 7 + 11 = 23.
2) Event A – an event that favors the condition.
You need to find the number of outcomes, where the removed ball is not white.
5 + 7 = 12.
3) Let’s find the probability that the taken ball is not white.
P (A) = 12/23 = 0.522.
Answer: P (A) = 0.522.
