Question 549462
The prob of getting a nickel is 11/20
Now one coin is removed but we still have 4 dimes so the prob of getting a dime is 4/19
and a nickel will be 10/18 since there is one nickel gone and two coins gone

We multiply these probabilities together and get {{{11/20*4/19*10/18}}} which after some multiplication of fractions (top times top bottom times bottom) and simplifying we get 11/171
