To do:

We have to fill in the blank.

Solution:

The total number of possible outcomes$=100$.

Number of outcomes of scoring 70 marks $=1$

This implies,

The total number of favourable outcomes$=1$.

We know that,

Probability of an event=$ \frac{Number \ of \ favourable \ outcomes}{Total \ number \ of \ outcomes}$

Therefore,

The probability of scoring 70 marks in a 100 marks test $=\frac{1}{100}$.
