Answer:
1/22
Step-by-step explanation:
assuming that the marbles drawn are not replaced:
P(red) = 3/12 or 1/4
P(green) = 4/11
P(blue) = 5/10 or 1/2
multiply the probabilities together:
1/4 x 4/11 x 1/2 = 1/22
That would be called the quotient.
248 divided by 4 equals 62 miles per hour.
Selling 90 would reach her goal of $135 so she would need to sell 91 to exceed her goal
135/1.5=90 so 91*1.5=136.5
