Suppose a jar contains 10 red marbles and 36 blue marbles. If you reach in the jar and pull out 2 marbles at random, without replacement, find the probability that both are red.

i think c. but don't trust it.

step-by-step explanation:

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
