Question

At a carnival game, you may win an inflatable crayon, you may win a small stuffed animal, or you may win nothing at all. If the probability of winning nothing is 0.72 and the probability of winning a small stuffed animal is 0.19, what is the probability of winning an inflatable crayon? Express your answer as a decimal.

A:0.91
B:0.28
C:0.09
D:0.81

Answer 1

C:0.09

Explanation:

probability of winning nothing = 0.72 =
`(72)/(100)`

probability of winning a small stuffed animal = 0.19 =
`(19)/(100)`

probability of winning nothing + probability of winning a stuffed animal

=
`(72)/(100)` +
`(19)/(100)` =
`(91)/(100)`

probability of winning an inflatable crayon = 1 - 
`(91)/(100)`

=
`(100)/(100)` - 
`(91)/(100)`

=
`(9)/(100)`

= 0.09
