If 3 x 742 = 2,226, then A)3 ÷ 2,226 = 742

B)742 ÷ 2,226 = 3

C)742 ÷ 3 = 2,226

D)2,226 ÷ 742 = 3

A) 3 ÷ 2,226 = 742

Step-by-step explanation:

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
