A . P(A n B)= $\frac{11}{15}$

Step-by-step explanation:

Step :-

we know that P(A U B) = P(A) + P(B) - P(A n B) ........(1)

given that

$P(A) = \frac{2}{3}$

$P(B) = \frac{4}{5}$ , $P(AUB) = \frac{11}{15}$

substitute all these values in equation (1)

we get $\frac{11}{15} = \frac{2}{3} + \frac{4}{5} - P(A n B)$

$P(A n B) = \frac{10+12}{15} - \frac{11}{15}$

$P(A n B) = \frac{22-11}{15}$

$P(AnB) = \frac{11}{15}$
