Question

Gina has a bag of marbles with 5 different colors. She randomly selects a marble from

the bag and then returns the marble to the bag. She does this 300 times. The table
below shows her results.

Answer 1

`(7)/(20)`

Explanation:

Red marbles = 33

Blue marbles = 72

Probability of selecting red or blue marbles:

`33 + 72 = 105 \\ (105)/(300) = (7)/(20)`
