Question

A basket contain 5red rose and some white roses.if probability of drawing a white rose is double to that of redrose .find the number of white rose

Answer 1

Answer:

No of White Roses in Basket is 10

Step-by-step explanation:

Given: No of Red Roses in Basket = 5

           Probability of drawing white rose =  twice of Probability of red rose

To find: No. of White Rose

Let the no of White Rose be x

Then total no of Roses in basket = 5 + x

Probability of Red Rose =  $\frac{5}{5+x}$

Probability of White Rose = $\frac{x}{5+x}$

According to the question,

$\frac{x}{5+x}=2\times\frac{5}{5+x}$

$x=2\times5$

x = 10

Therefore, No of White Roses in Basket is 10
