Question

14 multiple choice 1 point mrs. davis has 20 coins in her purse. she has 6 pennies, 4 quarters, 3 dimes, and the rest are nickels. what would the theoretical probability be of picking a nickel from her purse? 7/20 2/5 1/4 9/20 3/20 1/2 1/20 3/10 1/10 1/5 clear my selection previous next

Explanation:

Step1: Calculate number of nickels

First, find the sum of non - nickel coins: $6 + 4+3=13$. Then, since there are 20 coins in total, the number of nickels is $20-(6 + 4+3)=20 - 13 = 7$.

Step2: Calculate probability

The probability $P$ of picking a nickel is the number of nickels divided by the total number of coins. So $P=\frac{7}{20}$.

Answer:

A. 7/20
