Question

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

marbles.
What is P(draw a blue or red marble)?
If necessary, round your answer to 2 decimal places.

Answer 1

P(red & blue) = 16/21

Answer 2

`0.76`

Explanation:

Probability = Number of favorable outcomes / Number of possible outcomes

There are
`16` favorable outcomes ( the
`8+8=16` marables that are either blue or red).

There are 21 possible outcomes ( the
`8+5+8=21` total marables).

P (draw a blue or red marable)
`=(16)/(21)` ≈
`0.76`
