Question

a bag contains 6 nickels, 5 dimes, and 4 quarters. if you draw 3 coins at random from the bag, without replacement, what is the probability that you will get a nickel, a quarter, and a nickel, in that order?

Answer 1

nickel=2/5, quarter=4/15, dime=1/3

Explanation:

Total number of coins in the bag = 6 + 5 + 4 = 15

Probability of getting a nickel =

`(6)/(15)`

which is also equivalent to

`(2)/(5)`

Probability of getting a quarter=

`(4)/(15)`

Probability of getting a dime=

`(5)/(15)`

which is equivalent to

`(1)/(3)`
