Answer 1

Hope this helps you :)

Answer 2

P( blue or red ) =
`(16)/(21)`.

Explanation:

Given : You randomly draw a marble from a bag of marbles that contains 8 blue marbles, 5 green marbles, and 8 red marbles.

To find : what is p(draw a blue or red marble).

Solution : We have given that

A beg contain blue marble = 8 .

Green marble = 5.

Red marble = 8 .

Total marble = 8 + 5 + 8 = 21.

Probability =
`(Favpurable\ outcome)/(Total\ outcome)`.

Probability of draw blue =
`(8)/(21)`.

Probability of draw red =
`(8)/(21)`.

P( blue or red ) =
`(8)/(21)` +
`(8)/(21)`.

P( blue or red ) =
`(16)/(21)`.

Therefore, P( blue or red ) =
`(16)/(21)`.
