3) 0.30

The probability a randomly selected student plays a sport given they work part time = 0.30

Step-by-step explanation:

Step(i):-

Given  'A' plays a sport

          B work part time

Given P(A) = 0.48

         P(B)  = 0.40

        P(A∩B) =0.12

       P(A∪B)¹ =0.24

Step(ii):-

By using conditional probability

and similarly

The probability a randomly selected student plays a sport given they work part time

Now

Final answer:-

The probability a randomly selected student plays a sport given they work part time = 0.30

if you mean

then it's c. 8, -7/3

but if you mean

then it is
