Question

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

Answer 1

Answer:

$0.76$

Step-by-step 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) $=\frac{16}{21}$ ≈ $0.76$

Answer 2

P(red & blue) = 16/21
