There are 5 quarters, 2 nickels and 3 dimes in a jar. One coin is randomly drawn, replaced and then another coin is drawn.

What is the probability of getting a quarter then a nickel?

 

Answer choices:

  • 3/20
  • 7/10
  • 1/10
  • 1/9

Prob of  getting a quarter on the first draw  =  (5/10)

 

Prob of getting a nickel on the second draw  = (2/10)

 

 

So......the overall probability  is   (5/10) (2/10  =  10 / 100  =    1 / 10
