Question

You have a bag of 15 marbles. 8 are red. 5 are blue. 2 are green. What is the probability of randomly pulling out a blue marble on the first try?

a. Because it is random, you can't calculate the probability
b.33%
c.3.3%
d.0.3 %

Answer 1

Answer:

33%

Step-by-step explanation:

to find the percentage of the probability you have to divide the number of diff ways of pulling out a blue marble to all the diff ways of pulling a random marble. the blue ones are 5 in total and that many are the diff ways of pulling out one, while all the diff ways of pulling a rando are equal to the total number of marbles, which is 15. so you just have to divide 5/15=1/3, whish is 33.(3)%
