Q. Data Analysis and Probability

\newline

Introduction to the probability of an event

\newline

15

\newline

bag with

10

marbles has

3

blue marbles,

2

yellow marbles, and

5

red marbles. A marble is chosen from the bag at random. What is the probability that it is ue?

\newline

Irite your answer as a fraction in simplest form.

Total marbles: Total marbles in the bag = $10$ ( $3$ blue + $2$ yellow + $5$ red).
Number of blue: Number of blue marbles = $3$ .
Probability calculation: Probability of picking a blue marble = $\frac{\text{Number of blue marbles}}{\text{Total number of marbles}}$ .
Calculate probability: Calculate the probability: $P(\text{blue}) = \frac{3}{10}$ .
