There are 9 long distance male runners and 5 long distance female runners. This makes a total of 9+5 = 14 long distance runners.
Out of this total of 14 long distance runners, there are 9 males. So the probability as a fraction is 9/14
If you need the answer in decimal form, then use a calculator to get 9/14 = 0.642857 which is approximate.
The area of D is given by:

The average value of f over D is given by:
The answer is 10 I just subtracted it so
It would be 6 x 6 x 6, since the number cube has six sides and it was thrown 3 times.
