Question

The slot numbers are laid out on a board on which gamblers place their bets. One column of numbers on the board contains all multiples of 3, that is, 3, 6 9,. , 36. You place a "column bet" that wins if any of these numbers comes up. What is your probability of winning?

Answer 1

0.3158

Explanation:

As we know the column of numbers on the board contains all multiples of 3, that is, 3, 6 9,. , 36., from 3 to 36 we have: 36/3 =12 values.

The probability of winning is the number of divided by the total possible outcomes:

=> P (multiple of 3) =
`(#favorable outcomes )/(# possible outcomes)` =
`(12)/(38)` ≈0.3158
