Question

A and B are two events associated with random experiment for which P(A) = 0.36, P(A or B) = 0.90 and P(A and B) = 0.25. Find (i) P(B), (ii) P(A' ∩B ' )

Answer 1

P(B )= P(A or B)-P(A)
P(B)= 0.90-0.36 = 0.54
sorry i didn't understood the second one....

Answer 2

Answer:

$0.54$

Step-by-step explanation:

P(B )= P(A or B)-P(A) P(B)

= 0.90-0.36 = 0.54
