Question

Please help fast. I don't know what to do

Answer 1

39/143 (B)

Explanation:

All the boys who play football, wrestle, or both equals 18 + 12 + 9 = 39

All of the boys are the boys who play football, wretle, or both (39) + the number of outlier boys, (104) = 143 boys in total.

There is a probability of 39/143 that a boy will wrestle or football.

Answer 2

\frac{30}{104}

Explanation:

9 is the number of boys who play football AND wrestle. 18 is the mumber of footballers, and 12 is the number of wrestlers.

18 + 12, or 30, is the number of boys who EITHER play football or wrestle.

The total number of boys playing sports is 104, so 30 out of 104 boys either play football or wrestle.

You can write this in fraction form as
`(30)/(104)`.
