Question

A man has 6 quarters, five dimes and three nickels in his pocket. He pulls out one coin. What is the probability that the coin is not a dime

Answer 1

To find the probability we need to start by defining the event,

`\text{event}=\text{ coin is not a dime}`

then we find the possible outcomes, if the coin is not a dime it can be a quarter or a nickel.

then we find the possible outcomes

`6+3=9`

and the total outcomes

`6+5+3=14`

then the probability is going to be

`(9)/(14)`
