Question

What is the probability that a randomly selected child from this group will have red hair, given that he has straight hair? (Enter your answer as a fraction.)

Answer 1

Answer:

Your question was incomplete, as the values are not given.

I guess these are the values you are talking about.

Hair Type   Brown   Blond   Black    Red    Totals

Wavy           20           5          15         3        43

Straight        80          15         65        12       172

Totals          100         20         80        15       215

Now w have to find out the probability of a child with red, straight hair.

Total no of children with straight hair are = 172

The children having straight red hair = 12

The probability of selected child = 12/172.
