A bag contains 3 red balls and 5 black balls. A ball is drawn at random from the bag. What is the probability that the ball drawn is (i) red ? (ii) not red?

Explanation

To solve the problem step by step, we will calculate the probabilities of drawing a red ball and not drawing a red ball from the bag.

### Step 1: Determine the total number of balls in the bag.
- The bag contains 3 red balls and 5 black balls.
- Total number of balls = Number of red balls + Number of black balls = 3 + 5 = 8.

### Step 2: Calculate the probability of drawing a red ball.
- The probability of an event is given by the formula:
