Question

If there are 10 apples, 10 oranges and 10 mangoes in a fruit basket, then find the probability of not picking a mango.

• A. $\frac{1}{3}$
• B. $\frac{2}{3}$
• C. $\frac{1}{4}$
• D. $\frac{3}{4}$

Answer 1

The correct option is B $\frac{2}{3}$

Number of mangoes = 10

Total number of fruits = 10 + 10 + 10 = 30

Probability of picking a mango = $\frac{\text{Number of mangoes}}{\text{Total number of fruits}}$

Probability of picking a mango = $\frac{10}{30}=\frac{1}{3}$

Probability of not picking a mango = $1–\frac{1}{3}=\frac{2}{3}$.
