Solve for s.

p=4s

Flip the equation.

4s=p

Divide both sides by 4.

4s/4=p/4

s=1/4p

there are 9 dimes in a total of 8+9+8=25 coins

The probability to choose one first is 9/25

Now there are 8 dimes in 24 coins and the probability to get a second dime is 8/24=1/3

The solution will be: (9/25)x(1/3)=3/25 then the answer is "B"
