John has coins in a jar. Five of the coins are pennies, 8 are dimes, and 3 are quarters. John randomly selects a coin from the jar and without replacing it randomly selects another coin. What is the probability that he selects a dime then a quarter?

b.-4 units

all you   do is count how many times you move

x-150=475   x=625

step-by-step explanation:

if the bike after the sale ($150) is $475 then just simply add 150 to 475.

time is equal to distance over rate so

t = d/r

need a little bit more information for the second question.
