Question

A bag contains 12 red balls and 10 blue balls. a ball is drawn at random. the probability that ball drawn is red is

Answer 1

total number of balls = 12+10
=22
total number of red balls = 12

the probability that ball drawn is red is = 12/22
=6/11

Answer 2

Answer:

$Probability\:of \: getting \\ red \: ball = \frac{6}{11}$

Step-by-step explanation:

$Total \: number \:of \\ balls \: in \: a \: bag = 12(red)+10(blue) \\=22\\Total \: number \: of\\possible\: outcomes = 22--(1)$

$Favourable \: outcomes = 12--(2)$

$Now,\\Probability \: ball\:drawn \:red = \frac{(2)}{(1)}$

$=\frac{12}{22}\\=\frac{6}{11}$

Therefore,

$Probability\:of \: getting \\ red \: ball = \frac{6}{11}$
