Question

Suppose A and B are dependent events. If p(A/B)=0.25 and p(B)=0.4 what is p(AandB) A. 0.1
B. 0.4
C. 0.45
D. 0.15

Answer 1

The answer for apex is 0.1

Answer 2

Answer:

P(A and B) is 0.1

Step-by-step explanation:

Given : $P(A/B)=0.25 and P(B)=0.4$

To Find : What is P(A and B)

Solution :

We are given that A and B are dependent events

Formula : $P(A \text{and B})=P(B) \times P(A|B)$

$P(A \text{and B})=0.4 \times 0.25$

$P(A \text{and B})=0.1$

Hence P(A and B) is 0.1
