Question

jenn has 15 quarters, 10 dimes, 17 nickels, and 30 pennies all in a bowl. what is the probability of randomly drawing out a nickel?
o $\frac{5}{21}$
o $\frac{7}{12}$
o $\frac{3}{21}$
o $\frac{17}{72}$

Explanation:

Step1: Calculate total number of coins

$15 + 10+17 + 30=72$

Step2: Calculate probability of drawing a nickel

The probability $P$ of an event is given by the formula $P=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$. Here, the number of favorable outcomes (drawing a nickel) is 17 and the total number of outcomes (total number of coins) is 72. So $P=\frac{17}{72}$.

Answer:

$\frac{17}{72}$
