#### Question

A die is thrown. If A is the event that the number on upper face is less than 5, then write sample space and event A in set notation.

#### Solution

The sample space (S) is

S = {1, 2, 3, 4, 5, 6}

No. of sample points = n(S) = 6

Let A be the event of getting numbers less than 5.

∴A = {1, 2, 3, 4}

⇒ n(A) = 4
