Question

1. Given that for two events A and B, P (A) = 3/5, P (B) = 2/3 and P (AUB) = 3/4, what is P (A/B)?
(a) 0.655
(b) 13/60
(c) 31/60
(d) 0.775

Answer 1

Answer:

hope my answer helps you friend .

marks as brainlest please

Step-by-step explanation:

P(A|B) = P(A&B)/P(B) So first we have to find P(A&B) P(AUB) = P(A) + P(B) - P(A&B) 3/4 = 3/5 + 2/3 - P(A&B) Multiply through by 60 45 = 36 + 40 - 60P(A&B) 45 = 76 - 60P(A&B) -31 = -60P(A&B) 31/60 = P(A&B) Go back to P(A|B) = P(A&B)/P(B) P(A|B) = (31/60)/(2/3) P(A|B) = (31/60)(3/2) P(A|B) = 31/40

Answer 2

option d.

Step-by-step explanation:

its that you have to remind P(A/B)= P(A&B)/P(B)
