Mildred has a bag of coins. The bag contains 10 dimes, 5 nickels, and 1 penny. She will randomly select 2 coins form the bag one at a time without replacement. What is the probability that Mildred will select a dime first and then a penny?A. 12083B. 1611C. 1285D. 241
Q. Mildred has a bag of coins. The bag contains 10 dimes, 5 nickels, and 1 penny. She will randomly select 2 coins form the bag one at a time without replacement. What is the probability that Mildred will select a dime first and then a penny?A. 12083B. 1611C. 1285D. 241
Determine total number of coins: Determine the total number of coins in the bag.Mildred has 10 dimes, 5 nickels, and 1 penny, so the total number of coins is 10+5+1.Total number of coins = 16.
Calculate dime selection probability: Calculate the probability of selecting a dime first.Since there are 10 dimes out of 16 coins, the probability of selecting a dime first is 1610.Probability of first dime = 1610.
Calculate penny selection probability: Calculate the probability of selecting a penny second, after a dime has been selected.After selecting a dime, there are now 15 coins left in the bag, and only 1 of them is a penny.Probability of second penny = 151.
Calculate combined probability: Calculate the combined probability of both events happening in sequence (selecting a dime first and then a penny).To find the combined probability, multiply the probability of the first event by the probability of the second event.Combined probability = (1610)×(151).
Perform multiplication for combined probability: Perform the multiplication to find the combined probability.Combined probability = (1610)×(151)=(16×15)10=24010.
Simplify fraction for final probability: Simplify the fraction to find the final probability. 24010 can be simplified by dividing both the numerator and the denominator by 10.Final probability = 241.
