You can use the cosine rule for this - you might have to change some of the letters around for it to make sense though. Hope this helps!

Answer:

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

$P(B/A) = \frac{P(BnA}{P(A)}$

and similarly $P(A/B) = \frac{P(AnB}{P(B)}$

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

Now $P(A/B) = \frac{P(AnB}{P(B)}$

$P(A/B) = \frac{0.12}{0.40}= 0.30$

Final answer:-

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