Question

$90\%$ of the mangoes in a bag are good. If a mango is chosen randomly from the box, find the probability of getting a bad mango.

• A. $\frac{9}{100}$
• B. $\frac{1}{100}$
• C. $\frac{9}{10}$
• D. $\frac{1}{10}$

Answer 1

The correct option is D $\frac{1}{10}$

90% of the mangoes in a bag are good.

The number of bad mango are $N=100-90=10\%$

Therefore the probability of getting a bad mango $P\left(E\right)=\frac{N}{100}=\frac{10}{100}=\frac{1}{10}$
