Answer: 70/1001
Step-by-step explanation:
Choosing 4 boys from total of 8 boys is a combination of 8 when 4 is taken at a time:
8C4 = 8!/4!4!
= 70
Since they are all boys, that means we are choosing 0 girl from the 6 girls.
6C0 = 6!/6!0!
= 1
Choosing 4 students from a total of 6+8=14 students is a combination of 14 when 4 people is taken at a time:
14C4 = 14!/10!4!
= 1001
This will give a probability of:
(70 × 1)/1001
= 70/1001
