Question

A jar contains 50 marbles, 21 are blue, 15 are yellow, and the rest are red. What is the probability that you pick out a blue marble?

Answer 1

The probability of drawing a red marble = 2/5. The probability of drawing a blue marble is now = 1/4. The probability of drawing a red marble = 2/5.

Explanation:

Answer 2

42%

Explanation:

There are 21 blue marbles out of the 50. Divide 21 with 50:

21/50 = 0.42

Next, change the decimal to a percentage. To do so, move the decimal point to the right two place values and slap a percentage sign onto it:

0.42 = 42%

42% is your probability of picking a blue marble.
