Question

Suppose a jar contains 15 red marbles and 19 blue marbles. If you reach in the jar and pull out 2 marbles at random at the same time, find the probability that both are red.

Answer 1

Answer:
`\bold{(35)/(187)}`

Explanation:

1st marble and 2nd marble

`(15\ red)/(34\ total)`
`*`
`(14\ red)/(33\ total)`
`=(15* 14)/(34* 33)=(5* 7)/(17* 11)= \boxed{(35)/(187)}`
