Answer :
Answer:
Boy = 40%
Girl = 66.6%
Step-by-step explanation:
1) Work out probability that student is a boy who wears cap
8 boys out of 20 wears a cap so to find the probability we have to do 8 divided by 20
- 8 ÷ 20 = 0.4
- 0.4 × 100 = 40%
2) Work out probability for girls who doesn't wear spectacles
To find the probability of girls who doesn't wear spectacles we have to do 8 divided by 12
- 8 ÷ 12 = 0.666...(recurring)
- 0.666...(recurring) × 100 = 66.6%
Hope this helps, have a lovely day! :)
