Explanation / Answer

Answer to #3)

7 pennies , 4 nickels and 5 dimes

Total = n = 7+4+5 = 16

P(all 3 dimes) = number of ways of selecting dimes / total number of ways of selecting any three coins

Number of ways of selecting 3 dimes out of 5 = 5C3

Number of ways of selecting any three coins out of 16 = 16C3

P(all three dimes) = 5C3 /16C3

P(all three dimes) = 10 / 560

P(all three dimes) = 1/56

.

Answer to #4)

2 pennies and 1 dime

Number of ways of selecting 2 pennies = 7C2 = 7*6/2 = 21

Number of ways of selecting 1 dime = 5C1 = 5

Total number of ways of selecting 3 coins = 16C3 = 16 *15 * 14 / (3*2) = 560

.

P(2 pennies and 1 dime) = 21 * 5 / 560

P(2 pennies and 1 dime) = 3/16

.

Answer to #5)

Number of ways of selecting 1 nickel = 4C1 = 4

Number of ways of selecting 1 penny = 7C1 = 7

Number of ways of selecting 1 dime = 5C1 = 5

Total number of ways of selecting 3 coins = 16C3 = 560

P(1 dime, 1 nickel and 1 penny) = (4 * 7 * 5) / 560

P(1 dime, 1 nickel and 1 penny) = ¼

.

Answer to #6)

1 dime and 2 nickels

Number of ways of selecting 2 nickels = 4C2 = 4*3/2 = 6

Number of ways of selecting 1 dime = 5C1 = 5

Total number of ways of selecting 3 coins = 16C3 = 560

P(1 dime and 2 nickels) = 6 * 5 / 560

P(1 dime and 2 nickels) = 3/56
