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

Answer:

$\frac{7}{20}$

Step-by-step explanation:

Red marbles = 33

Blue marbles = 72

Probability of selecting red or blue marbles:

$33 + 72 = 105 \\ \frac{105}{300} = \frac{7}{20}$
