Question

a hat contains 12 quarters, 13 nickels, and 5 pennies. find the theoretical probability of pulling out a quarter. p(q) = ? round your answer to the nearest hundredth.

Explanation:

Step1: Calculate total number of coins

$12 + 13+5=30$

Step2: Calculate probability of pulling a quarter

$P(Q)=\frac{\text{Number of quarters}}{\text{Total number of coins}}=\frac{12}{30} = 0.40$

Answer:

$0.40$
