Question

A bag contains 6 green balls and n yellow balls. If probability of drawing a yellow ball is five
times that of a green ball, then n is equal to?​

Answer 1

Answer:

6×5=30

n=30

I am bravest

Answer 2

Given:

The number of green balls in the bag = $6$

The number of yellow balls in the bag = $n$

$P\;(Yellow\;ball)\;=\;5P\;(Green\;ball)$

To find:

The value of $n$

Step-by-step explanation:

There are $6$ green balls and $n$ yellow balls

∴ Total number of balls = $6\;+\;n$

$P\;(green\;ball)\;=\;\frac6{n+6}$

$P\;(yellow\;ball)\;=\;\frac n{n+6}$

∵ $\frac n{n+6}\;=\;5\;(\frac6{n+6})$

$\frac n{n+6}\;=\;\frac{30}{n+6}\\\\\\;n\;=\;30$

Answer:

Therefore, the value of $n$ is $30$
