Rashid [163]

Answer:

1/3

Explanation:

The first thing to do is to figure out all possibilities.

I'll use f for female and m for male.

The possible outcomes are: 5f,  4f 1m,  3f 2m,  2f 3m,  1f 4m,  or 5m.

Since there are 6 possible outcomes, and 2 of the outcomes are 2 males and 3 females or 3 males and 2 females, the probability is 2/6 or 1/3!
