Evaluate :
`(1)/(3!)+(1)/(4!)+(1)/(5!)`

Explanation

To evaluate the expression \( \frac{1}{3!} + \frac{1}{4!} + \frac{1}{5!} \), we will follow these steps:

### Step 1: Calculate the factorials
First, we need to calculate the factorials of 3, 4, and 5.

- \( 3! = 3 \times 2 \times 1 = 6 \)
- \( 4! = 4 \times 3 \times 2 \times 1 = 24 \)
- \( 5! = 5 \times 4 \times 3 \times 2 \times 1 = 120 \)
