To find P(A U B), we can use the formula P(A U B) = P(A) + P(B) - P(A n B).
Given that P(A) = 8/15, P(B) = 6/15, and P(A n B) = 1/5, we can substitute these values into the formula:
P(A U B) = 8/15 + 6/15 - 1/5
Simplifying the expression, we get:
P(A U B) = 14/15
So, the probability of A union B is 14/15.
