a hat contains 12 quarters, 13 nickels, and 5 pennies. find the theoretical probability of pulling out a penny. p(p) = ? round your answer to the nearest hundredth.
Answer
Explanation:
Step1: Calculate total number of coins
$12 + 13+5=30$
Step2: Calculate probability of pulling a penny
$P(P)=\frac{\text{Number of pennies}}{\text{Total number of coins}}=\frac{5}{30}=\frac{1}{6}\approx 0.17$
Answer:
$0.17$
