Question

Given that the econd tudent choen i a girl, what i the probability that the firt tudent wa alo a girl?

Answer 1

50% or 1/2

Step-by-step explanation:

Assuming there is a 50/50 split of boys and girls in a class, the answer is 50%

We know this because the question doesn't specify if the selection is with or without replacement, so we can assume either (so I assume with replacement).

With replacement would mean that the first and second students chosen are independent events and that they do not impact each other. Thus, we are just finding the probability that we choose a girl in a 50/50 split class.

This means our answer is 50%
