Explanation:
A, B, and C have the same area. So P(A) = 1/3 and P(B) = 1/3, which means P(A or B) = 2/3.
P(success) = 2/3 and P(failure) = 1/3.
The probability of 2 failures is:
P = (1/3)² = 1/9
The probability of 2 successes is:
P = (2/3)²= 4/9
The probability of 1 success and 1 failure can be found either with binomial probability, or simply by subtracting the probabilities we found earlier from 1.
P = 1 - 1/9 - 4/9
P = 4/9
So the answer is the one in the bottom left corner.
