P(Blue) = 0.3

Step-by-step explanation:

Given

Red = 5

Blue = 3

Orange = 2

Required

Probability that the first marble is Blue

First, the total number of marble has to be calculated;

$Total = Red\ Marble + Blue\ Marble + Orange\ Marble$

Total = 5 + 3 + 2

Total = 10

The probability of Blue being the first is calculated as thus;

$P(Blue) = \frac{n(Blue)}{Total}$

$P(Blue) = \frac{3}{10}$

P(Blue) = 0.3

Hence, the required probability is 0.3
