Mathmatics Question #1

Question

You select a letter randomly from a bag containing the letters S, P, I, N, N, E, and R. Find the probability of selecting an S.

Answer 1

There are 7 objects total (two are N), and there is only one S, so there is 1 chance in 7 of  picking the S.

 

Probability = 1/7

Answer 2

There are 6 letters altogether but only one is an S. The probability is 1/6.
