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?
+163 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
