Question

Jar contains 3 red marbles, 7 green marbles and 10 white marbles. If a marble is drawn from the jar at random, what is the probability that this marble is white

Answer 1

1/2 is. probability for getting a white

=10/3+7+10

=10/10

=1/2

Answer 2

Answer:

Step-by-step explanation:

• Jar having Red marbles=3
• Jar having Green marbles=7
• Jar having White marbles=10

S0, Total balls in the jar = 3+7+10=20

Find: p(white marble)=?

p(white marble)=white marble/total marble

                         = 10/20 => 1/2

                         = 0.5  0R  50%
