Question

A bag has 14 red marbles and 10 white marbles. Rosa

randomly picks one marble from the bag. What is the
probability that a white marble is selected?

Answer 1

5/12 = 0.41666666666 = 0.42 = approx 42% (I don't know how your teacher wants you to answer, fraction/decimal/percentage)

Explanation:

There are 14 + 10 = 24 total marbles.

10 are white.

P(white) = 10/24 = 5/12 = 0.41666666666 = 0.42 = approx 42%

so 10/24 = 5/12 are white
