For a given interest rate, simple interest varies jointly as the principal and time. If $3000 left in an account for 5 years eamed interest of $900, then how much interest would be earned in 7 years?

blue marble is 15 times out of 50 = 15/50 reduces to 3/10

landing on tails is 24 out of 50 = 24/50 reduces to 12/25

to find the probability of both multiply together:

3/10 x 12/25 = 3 x 12 / 10 x 25 = 36/250

if you multiplied the numerator and denominator by 10 you get 360/2500.

the answer is 360/2500
