Question

A class consisting of 4 graduate and 12 undergraduate students is random divided into 4 groups of 4. what is the probability that each group includes a graduate student? give your answer accurate to 2 decimal places.

Answer 1

Total = 16
Graduates = 4


`(4)/(16) = (1)/(4)`

`(1)/(4) / 4 \\ = (1)/(4) * (1)/(4) \\ = (1)/(16)`

`(1)/(16) = 0.0625`
Rounding off to 2 decimal places,
Answer is 0.06

Hope this helps. - M
