Question

A box contains 10 red flowers, 6 white flowers, 4 pink flowers and 8 yellow flowers. Swetha picked a flower randomly from the box. What is the probability that Swetha picks a pink flower?

• A. True
• B. False
• C. $\frac{1}{7}$
• D. $\frac{1}{9}$

Answer 1

The correct option is C

$\frac{1}{7}$

Given,

Number of red flowers = 10

Number of white flowers = 6

Number of pink flowers = 4

Number of yellow flowers = 8

Total number of flowers in the box = 10 + 6 + 4 + 8 = 28

$\Rightarrow$ Total number of outcomes = 28

Number of favourable outcomes = 4

Probability of an event, P(E) = $\frac{\text{number of favourable outcomes}}{\text{total number of outcomes}}$

P(picking a pink flower) = $\frac{4}{28}=\frac{1}{7}$

Therefore, the probability that Swetha picks a pink flower is $\frac{1}{7}$.
