Question 947658
chickens are either red or black.
10% are roosters.
50% of roosters are black.
probability a chicken is both a rooster and black will be 10% * 50% = 5%.
for example:
assume 100 chickens.
10% are roosters.
that makes 10 that are rooster.
50% of the 10 are black.
that makes 5 of the roosters that are black.
you have 5 chickens out of 100 that are both black and a rooster.
5/100 = .05 = 5%.
probability that you randomly pick a chicken out of the group of chickens and that the chicken is both black and a rooster is 5%.
