X is taking up subjects Mathematics, Physics and Chemistry in the examination. His probabilities of getting grade A in these subjects are 0.2, 0.3, and 0.5 respectively. Find the probability; that he gets (i) Grade A in all subjects (ii) Grade A in no subject (iii) Grade A in two subjects

Explanation

To solve the problem step by step, we need to calculate the probabilities for each of the scenarios given.

### Given:
- Probability of getting Grade A in Mathematics (P(M)) = 0.2
- Probability of getting Grade A in Physics (P(P)) = 0.3
- Probability of getting Grade A in Chemistry (P(C)) = 0.5

### Step 1: Probability of getting Grade A in all subjects
