Question

A jar has ten coins in it. Two of them are nickels, three of them are not pennies, three of them are quarters, and two of them are dimes. If one of coin is taken out of the jar randomly, what is the probability that it will be a dime?

Answer 1

0.2 is the probability that a randomly picked coin from jar is a dime.

Explanation:

We are given the following in the question:

Total number of coins in the jar = 10

Number of nickels = 2

Number of quarters = 3

Number of dimes = 2

Coins that are not pennies = 3

Formula:

`\text{Probability} = \displaystyle\frac{\text{Number of favourable outcomes}}{\text{Total number of outcomes}}`

P(Dime) =

`=\frac{\text{Number of dimes}}{\text{Total number of coins}}\\\\=(2)/(10) = 0.2`

0.2 is the probability that a randomly picked coin from jar is a dime.
