Question

if p(a) =02.5, P(b)=0.15 and P( a and b) = then P(A/b) is
(a):0.66666666667
(b):0.57142857143
(c):0.85714285714
(d):0.15384615385​

Answer 1

Answer:

a

Step-by-step explanation:

a is the correct answer

Answer 2

Step-by-step explanation:

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

P(A or B) = 0.5 + 0.4 - 0.3

P(A or B) = 0.9 - 0.3

P(A or B) = 0.6

So (a):0.66666666667

Is the correct answer
