Question

a bag contains 6 red balls,8 white ball,5 greeen ball and 3 black ball.one ball is drawn at rondom from the.find the probability that the ball drawn is;​

Answer 1

Answer:Total ball-6+8+5+3=22 balls

red balls probablity=6/22=3/11

White balls probablity=8/22=4/11

green balls probablity=5/22

black balls probablity=3/22

Answer 2

Correct Question:

A bag contains 6 red balls. 8 white balls, 5 green balls and 3 black balls. One ball is drawn at random from the bag. find the probability that the ball is red or black.

Your Answer:

Given:-

• Red balls = 6
• White balls = 8
• Green ball = 5
• Black ball = 3
• One ball is drawn at random

To find:-

• The probability that the ball is red or black.

Solution:-

$\tt Total\:chances\: of \: outcomes\\\\ \tt = 6+8+5+3 \\\\ \tt = 22$

$\tt Favourable\: out comes \\\\ \tt = 6+3\\\\ \tt=9$

$\tt P(E)=\dfrac{Favourable \:outcomes}{Total number of Outcomes} \\\\ \tt P(E)=\dfrac{9}{22}$

So probability is 9/22
