Question

There are 3 red ,7 green and 12 white marbles
in a jar One marble is drawn at random Find
the prăbability that marble drawn is not
green​

Answer 1

Answer:

given that:

red marbles=3

green marbles=7

white marbles=12

find: probability of drawn marble is not green=?

total balls in the jar=3+7+12

=22

Probability of drawn a green marble = 7/22

Probability of drawn a marble ( is not green) = 1-7/22

=15/22
