Answer:
2/3
Step-by-step explanation:
There are a couple of different ways that division of fractions can be done.
1) "invert and multiply"

__
2) use the numerators when the denominators are the same

First find out how many cm at in an foot then convert it over to cm or feet. Then compare. The larger number is the wider car.
P(all 4 are male) = 1/2^4 = 1/16 ( assuming probability of 1 male = 1/2)
P( 3 are male) = 1/2^4*4 = 1/4
The rest will have at least 2 females
So probability of at least 2 females) = 1 - 1/16 - 1/4 = 1 - 5/16 = 11/16 answer
