Answer 1

10/21

Answer 2

could you explain how you got htat

Answer 3

hypergeometric distribution

Answer 4

The total group size is (5+4) = 9

We need to select 5 from this group of 9

The ways to do this are 9C5 = 126

Answer 5

Now, we are interested in the case where there are 3males (and thus by duduction 2 females).

So we need to choose 3 males out of the 5males available.

We also need to select 2 females out of the 4 females available

The ways we can satisfy the condition is thus ( 5C3 x 4C2) = 10x6=60

Thus the answer is 60/126 = 10/21
