Question

A bag contains 3 red, 6 blue, 5 purple, and 2 orange marbles. One marble is selected at random. What is the probability that the marble chosen is blue? Answer with a percentage or a simplified ratio.

Answer 1

b. The probability of choosing a blue marble is blue/total.The number of blue marbles is 6, and the total number of marbles is 16 (3 + 6 + 5 + 2 = 16).Therefore, the probability of choosing a blue marble is 16/16 = 3/8.

Answer 2

`P(blue)=37.5\%`

Explanation:

-Probability is the likelihood of an event occurring.

-The total number of events is:

`Total=3+6+5+2\\\\=16`

-The total number of blue events is:

`Blue=6`

#Probability of a blue is thus calculated as:

`P(Blue)=(Blue)/(Total)\\\\=(6)/(16)\\\\=0.375\\\\=37.5\%`

Hence, the probability of choosing a blue marble at random is 37.5%
