a jar contains 65 pennies 27 nickels 30 dimes and 18 quarters a coin is randomly selected from the jar find each probability

Answers

The required probabilities are $P(\text{pennies})=(13)/(28),P(\text{nickels})=(27)/(140),P(\text{dimes})=(3)/(14),P(\text{quarters})=(9)/(70)$ .

Given:

Pennies = 65

Nickels = 27

Dimes = 30

Quarters = 18

To find:

The probability of each.

Solution:

The probability formula:

$\text{Probability}=\frac{\text{Favorable outcome}}{\text{Total outcomes}}$

Total number of coins:

$65+27+30+18=140$

The probability of selecting Pennies is:

$P(\text{pennies})=(65)/(140)$

$P(\text{pennies})=(13)/(28)$

The probability of selecting nickels is:

$P(\text{nickels})=(27)/(140)$

The probability of selecting dimes is:

$P(\text{dimes})=(30)/(140)$

$P(\text{dimes})=(3)/(14)$

The probability of selecting quarters is:

$P(\text{quarters})=(18)/(140)$

$P(\text{quarters})=(9)/(70)$

Therefore, the required probabilities are $P(\text{pennies})=(13)/(28),P(\text{nickels})=(27)/(140),P(\text{dimes})=(3)/(14),P(\text{quarters})=(9)/(70)$ .
