Can you compute probability

 

A member of the junior varsity swim team will be elected as President. Each member is equally likely to be elected. The probability that a sophomore is elected is  the probability that a freshman is elected. Everyone on the junior varsity swim team is either a freshman or sophomore. What fraction of the swim team are sophomores?

I answered this problem recently

https://web2.0calc.com/questions/probability_53928#r1

here was my solution

probability is defined by the 

amount of times when it is true/ total amount of times (or false + true in most cases)

the total is 6! or 6*5*4*3*2*1

since we have the pair's of socks over 3 days we take every other integer to multiply

6*4*2

so if we take 6,4,2 out of the denominater

1/5*3*1

since 1*x = x we can take this out of the equation

5*3 = 15

the solution is 1/15
