Question

The probability of drawing a blue ball from a bag that contains 3 white balls, 8 blue balls and 5 red balls is

• A. P <= 0.25
• B. P < 0.5
• C. P = 0.5
• D. P > 0.5

Answer 1

The correct option is A

P <= 0.25

Given,

Number of white balls = $3$

Number of blue balls = $8$

Number of red balls = $5$

Total number of outcomes $n\left(S\right)$= $16$

Events favouring for drawing blue ball $n\left(E\right)$ = $8$

Probability of occuring an event P(E) = $\frac{n\left(E\right)}{n\left(S\right)}$ = $\frac{8}{16}$ = $\frac{1}{2}$

Therefore, probability of drawing a blue ball is $\frac{1}{2}$.
