Answer 2

Let number of friends Olive has = S

She wants to select a friend for a trip.

1. Probability of selecting a friend out of S friends

`=\frac{\text{Total favorable Outcome}}{\text{Total possible outcome}}\\\\=(1)/(S)`

Ok, suppose out of S friends P are male and Q are female.

S=P +Q

2. Probability of selecting 1 male friend out of S friends which includes P male and Q female

`\frac{{}_(1)^(P)\textrm{C}}{S}`

3. Probability of selecting 1 Female friend out of S friends which includes P male and Q female

`\frac{{}_(1)^(Q)\textrm{C}}{S}`

These three are random methods.Other methods of finding probability of choosing a friend can be non Random.
