A and B are two events. Let P(A)=0.5 , P(B)=0.9 and P(A and B)=0.15 .

Nana76 [90]

Answer:

option-C

Step-by-step explanation:

we are given

Let P(A)=0.5

P(B)=0.9

P(A and B)=0.15

we know that

$P(A|B)=\frac{P(Aand B)}{P(B)}$

now, we can plug values

$P(A|B)=\frac{0.15}{0.9}$

$P(A|B)=0.16666$

but we have

P(A)=0.5

we can see that both are not equal

$P(A|B)\neq P(A)$

so, A and B are not independent

so, option-C........Answer
