Question

28. A box contains 3 blue, 2 white and 4 red marbles. If a marble is drawn at random
from the box, what is the probability that it will be (i) white (1) blue (in) red.​

Answer 1

Answer :-

• Probability of white marbles = 1/3
• Probability of blue marbles = 2/9
• Probability of red marbles = 4/9

Step-by-step explanation:

To Find :-

• The probability of white, blue and red marbles.

Given that,

• No. of white marbles = 3
• No. of blue marbles = 2
• No. of red marbles = 4

We know,

Probability = Number of favourable outcomes/Total number of outcomes,

∴ A . T . Q,

Probability of white marbles in box contains :-

⇒ 3/9

⇒ P[white marbles] = 1/3

Probability of blue marbles in box contains :-

⇒ P[blue marbles] = 2/9

Probability of red marbles in box contains :-

⇒ P[red marbles] = 4/9

Hence,

• Probability of white, blue and red marbles are 3/9, 2/9 and 4/9 respectively.
