Question

A bag contains yellow and black balls. The probability of getting a yellow ball from the bag of balls is $\frac{2}{3}$. What is the probability of not getting a yellow ball?

• A. $\frac{1}{3}$
• B. $\frac{2}{3}$
• C. $\frac{5}{3}$
• D. $\frac{7}{3}$

Answer 1

Answer: (A)

$\frac{1}{3}$

The probability of getting a yellow ball from the bag of balls is $\frac{2}{3}$.
Therefore, the probability of not getting a yellow ball
Using Complement property of probability,
P(ball is not yellow) $=$ $1-\frac{2}{3}=\frac{1}{3}$
Therefore, the probability of not getting a yellow ball is $\frac{1}{3}$.
