Question

A bag contains 5 red and 3 blue balls. If one ball is drawn at random, what is the probability that it is red?

• A. \( \frac{3}{8} \)
• B. \( \frac{5}{8} \)
• C. \( \frac{3}{5} \)
• D. \( \frac{2}{5} \)

Hint:

For probability, calculate \( P(\text{event}) = \frac{\text{Favorable outcomes}}{\text{Total outcomes}} \), ensuring all outcomes are counted.

Answer 1

The Correct Option is B

The bag contains 5 red and 3 blue balls, so the total number of balls is \( 5 + 3 = 8 \). The probability of drawing a red ball is: \[ P(\text{red}) = \frac{\text{Number of red balls}}{\text{Total balls}} = \frac{5}{8} \] Thus, the probability is: \[ \boxed{\frac{5}{8}} \]
