Question

In a certain​ region, the probability of a baby being born a is instead of 0.5. Let A denote the event of getting a when a baby is born. What is the value of ​?

Answer 1

`P(\bar A) = 0.5`

Explanation:

Given

`P(A) = 0.5`

Required

`P(\bar A)`

To do this, we make use of complement rule:

`P(\bar A) = 1 - P(A)`

So, we have:

`P(\bar A) = 1 - 0.5`

`P(\bar A) = 0.5`
