Cards numbered from 11 to 60 are kept in a box. If a card is drawn at random from the box, find the probability that the number on the drawn card is an odd number.

###### Advertisements

#### Solution

Total possible outcomes = {11, 12, 13, ...60} = 50

Favourable outcome for getting an odd number = {11, 13, 15, ......, 57, 59}

Total number of favourable outcomes (*n*) can be given by,

P (getting an odd number) `="Favourable outcomes"/"Total outcomes"=25/50=1/2`
