Two resistances `R_(1)=(15 pm 0.5) Omega" and "(20 pm 0.7)Omega` are connected in parallel. Calculate the total resistance of the combination and maximum percentage error.

Explanation

To solve the problem of finding the total resistance of two resistances connected in parallel and calculating the maximum percentage error, we will follow these steps:

### Step 1: Identify the Given Values
We have two resistances:
- \( R_1 = 15 \pm 0.5 \, \Omega \)
- \( R_2 = 20 \pm 0.7 \, \Omega \)

### Step 2: Use the Formula for Parallel Resistance
