Question

B) Attempt each of the following:
i) A bag contains 10 red marbles, 16 green marbles and 14 white marbles. Onem
drawn at random from the bag. Find the probability of getting :
a) a red marble
b a non red marble​

Answer 1

Answer:

a red marble = 10/40

a non red marble = 30/40

Answer 2

Total Marbles = 10+16+14= 40

Red Marbles = 10

Green Marbles = 16

White Marbles = 14

P( a red marble) = Favourable Outcomes / Total Outcomes

= 10/ 40

= 1/4

Not a red marble = 40+10= 30

P(not a marble) = Favourable/Total

= 30/ 40

= 3/4
