Question

A dies is tossed. find the odds against rolling a number greater than 4

Answer 1

A die has 1, 2, 3, 4, 5, 6.

Odds against = Number of failures : Number of successes

Number of failures = 1, 2, 3, 4 = 4

Number of successes = 5, 6 = 2

Odds against = Number of failures : Number of successes

Odds against = 4 : 2 = 2 : 1

So odds against = 2/1 =2
