Question

A bag contains 3 white and 5 black balls. If one ball is drawn, then the probability that is black is

• A. $3/8$
• B. $5/8$
• C. $6/8$
• D. $10/20$

Answer 1

The correct option is B

$5/8$

The explanation for the correct option:

The probability that the ball drawn is black

Total number of white balls = $3$

Total number of black balls = $5$

The sample space is the total number of balls, $n\left(S\right)=8$

The event is drawing a black ball,$n\left(E\right)=5$

Thus the probability that is black, $P\left(E\right)=\frac{5}{8}$

Hence, option(B) is correct.
