A translation
(I'm assuming that this isn't multiple choice since you didn't include the answer choices.)
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.
There are one 4/5 in 1 cus (1=5/5)
B
Because 2 sqrt5 is = to sqrt 20.
4^2=16, 6^2=36
