Answer 3

You need to start with the venn diagram and use those values to fill out the probabilities P(F), P(L), etc

Answer 4

Keep in mind that in the F circle, there are the values 3 and 47. So there are 3+47 = 50 females.

The sample size is 100
That must mean there are 100-50 = 50 males

Answer 5

The sample size is 100

There are 47+43 = 90 right-handed people

so that leaves 100-90 = 10 left-handed people

Answer 6

The 47 in the intersection of the F and R circles represents those who are female AND who are right-handed. So there are 47 right-handed females.

Answer 7

come to think of it, it might be easier to fill out the 2 way table first. Then use that to figure out the probabilities
