Answer: 0.1630
Explanation:
Number of quarters = 10
Number of dimes = 6
Number of nickels = 8
Total number = 10+6+8 = 24
Probability of choosing the first quarter will be: = Number of quarters/Total number of money
= 10/24 = 5/12
Since a quarter has been selected, the total number will reduce to 23 the next time a quarter is choosing and the number of quarters will now be 9. Therefore, the probability of choosing the second quarter will be: = 9/23
Therefore, the probability that two quarters are chosen random from the jar will be:
= 5/12 × 9/23
= 45/276
= 0.1630
