Probability of A 0.60 or B 0.45 the probability either is 0.80 find the probability of both

Respuesta :

Given info:
P(A) = probability of A
P(A) = 0.60
P(B) = 0.45
P(A or B) = 0.80

Use the given info to find....
P(A and B) = P(A) + P(B) - P(A or B)
P(A and B) = 0.60 + 0.45 - 0.80
P(A and B) = 1.05 - 0.80
P(A and B) = 0.25

Answer: 0.25

P(A) = 0.6

P(B) = 0.45

P(A||B) = 0.8

P(A and B) = P(A) * P(B) = 0.60 * 0.45 = 0.27
