Question

A jar contains 11 brown and blue marbles. A marble is drawn at random. What is the theoretical probability (as a percent) of Not drawing a blue marble

Answer 1

Step-by-step explanation:

Let the jar has x brown marbles

Therefore, no of blue marbles = 11 - x

Total marbles = 11

Probability of not drawing a blue marble = Probability of drawing a brown marble

$= \frac{x}{11} = \frac{x}{11} \times 100 = 9.09x \% \:$
