Question

Clearly define the sample space and then find the probability values for the number of males in a group of 5 people?

Answer 1

Let X be the number of males in a group of 5 people.

So X~ Bin ( 5, 0.5)

Sample space = { 0,1,2,3,4,5}

Probabilities:

1 ) P(X = 0 )

2 ) P(X = 1 )

3) P(X = 2 )

4) P(X = 3 )

5) P(X = 4 )

6) P(X = 5 )
