Question

A bad contains 2 red, 4 blue and 6 green balls. if one ball is drawn from the bag, what is the probability that it is red or green? select one:

Answer 1

Given- no. of red balls = 2
no. of blue balls = 4
no. of green balls = 6

Solution - Total no. of balls = 2+4+6=12

Now, probability that a ball drawn out is red =

no. of red balls/total no. of balls

=2/12 = 1/6


And, probability that the ball drawn out is green = 6/12 = 1/2 or 0.50


Also, probability that the ball drawn out is either a red or green ball = no. of red+no.of green balls/total no.of balls

=2+6/12
=8/12
=2/3.

HOPE THIS HELPS!!!!
