We are given the fact that he plays football, so the probability of his being a football player is 100%.
We know that 1/3 of the football players also play baseball, so the probability that he is also a baseball player is 1/3.
Ok so you multiply 22 square and then do the same for 10, do the negative of the square of 22 and then subtract it from the 10 and you should get another negative and it should be b=x the value of both and finally you divide the b and the value by the square root . An example would be a=8 + b = c= 20 going through the process you would get the answer of 18.33. I know I didn't explain this correctly so here's a link to help you with math problems.
