Question

B is 1-15
I is 16-30
N is 31-45
G is 46-60
O is 61 - 75

What is the odds against selecting a ball containing the letter G?

Answer 1

B is 1-15 means there are 15 balls of B
I is 16-30 means there are 15 balls of I
N is 31-45 means there are 15 balls of N
G is 46-60 means there are 15 balls of G
O is 61 - 75 means there are 15 balls of O

there are a total of 15+15+15+15+15 = 75 balls.
there are a total of 15 balls with G

the probability of selecting 1 ball that has a G on it is 15 out of 75. or 15/75
