Question

A bag contains 15 White balls, 5 Red balls. A ball is drawn at random. Probability in percentage that the drawn ball be a white ball is

• A. 75
• B. 25
• C. 70
• D. 80

Answer 1

The Correct Option is A

The total number of balls is: \[ 15 \, (white) + 5 \, (red) = 20 \, balls \] The probability of drawing a white ball is: \[ P(white) = \frac{15}{20} = \frac{3}{4} \] To convert this probability into percentage: \[ P(white) = \frac{3}{4} \times 100 = 75% \] The probability of an event is the ratio of favorable outcomes to total outcomes. Multiply by 100 to convert it to a percentage.
