Answer :

The probability of selecting a blue marble will be; 61.5%

What is the probability of selection?

Now, when we talk about probability here what we mean is the likelihood of an event happening.

Now, we are told that there are 5 green marbles and 8 blue marbles. Thus;

Total Number of Marbles = 8 + 5 = 13 marbles

Thus, probability of selecting a blue marble will be;

P(Blue Marble) = Number of Blue Marbles/Total Number of Marbles

Thus;

P(Blue Marble) = 8/13

P(Blue Marble) = 0.615 = 61.5%

Complete question is;
