Answer 1

a) the Probability p( red, red, red) is 0.83%.

b) the probability p(white, red, white) is 0.

Explanation:

The total number of marbles = 3+6+1.

=10.

a) to find the Probability p( red, red, red).

p( red, red, red)=
`(3C_(3) )/(10C_(3)).`

p( red, red, red)=
`(3)/(10)`×
`(2)/(9)`×
`(1)/(8)`.

p(red,red,red)= 0.0083.

p(red,red,red)=0.83%

b)to find the probability p(white, red, white).

p(white, red, white) is 0.

Since there is only one white.
