Answer :

**Concept Used:**

**Explanation:**

(i) Total number of balls in the bag = 8

No of red balls = 3

Let E be the event of getting a red ball, then

No of favourable outcomes = No of red balls = 3

No of possible outcomes = No of total balls = 8

The probability of the ball drawn to be red:

**Hence, the probability of a red ball is 3/8.**

(ii) We know that:

where E and are complementary events, as getting a red ball and not getting a red ball are complementary events

Hence,

The probability of not getting the red ball

= 1 - Probability of getting a red ball

= 1 – 3/8

= 5/8

**Hence, the probability of not red is 5/8.**
