# There are 6 marbles in a box with numbers from 1 to 6 marked on each of them.

(i) What is the probability of drawing a marble with number 2?

(ii) What is the probability of drawing a marble with number 5?

**Solution:**

Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.

Given, total number of marbles from 1 to 6 marked in a box = 6

Thus, total number of outcomes: n(S) = 6

We know that,

Probability = Number of favorable outcomes / Total number of outcomes

(i) Number of marbles marked with 2 = 1

Thus, number of favorable outcome : n(E) =1

Therefore, P(probability of drawing a marble with number 2) = n(E) / n(S)

= 1/6

(ii) Number of marbles marked with 5 = 1

Thus, number of favourable outcome: n(E) = 1

Therefore, P(probability of drawing a marble with number 5) = n(E) / n(S)

=^{ }1/6
