# A die is thrown. Let A be the event that the number obtained is greater than 3. Let B be the event that the number obtained is less than 5. Then, $$P(A \cup B)$$ is

## Solution :

A = {4. 5. 6}  and  B = {1, 2, 3, 4}

$$A \cap B$$ = 4

$$\therefore$$  $$P(A \cup B)$$ = P(A) + P(B) – $$A \cap B$$

$$\implies$$ $$P(A \cup B)$$ = 3/6 + 4/6 – 1/6 = 1
