Question

Leona has 4 nickels, 6 pennies, 4 dimes and 2 quarters in a change purse. Leona lets her little sister Daisy pick a coin at random. If Daisy is equally likely to pick each type of coin, what is the probability that her coin is worth more than five cents? Explain

Answer 1

Pennies are 1¢ each, nickels are 5¢ each,

dimes are 10¢ each, and quarters are 25¢ each.

There are 16 coins in all.

Of these 16 coins, 4 are dimes, and 2 are quarters. So 6 coins are each worth more than 5¢.

P(coin more than 5¢) =

P(dime or quarter) = 6/16 = 3/8
