Question

P(A) = 0.80, P(B) = 0.60. What is P(B | A)

Answer 1

`\sf P(B|A)=0.60`

Explanation:

Given:

• P(A) = 0.80
• P(B) = 0.60

If events A and B are independent then:

`\boxed{\begin{aligned} \sf P(A \cap B)&=\sf P(A)P(B)\\\sf P(A|B)&=\sf P(A)\\\sf P(B|A)&=\sf P(B)\end{aligned}}`

Therefore:

`\implies \sf P(B|A)=P(B)=0.60`
