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