Box A contains 25 slips of which 19 are marked Re.1 and others are marked Rs.5 each. Box B contains 50 slips of which 45 are marked Re.1 each and others are marked Rs.13 each. Slips of both boxes are poured into a third box and reshuffled. A slip is drawn at random. From the following choices, what is the probability that it is marked other than Re.1 ?

### Solution:

It is given that boxes contain some slips with Re.1, Rs.5, and Rs.13.
We have to find the probability that the marked slip is other than .
First we find the total number of slips.

are marked in Box and are marked in Box as Re.1.
So, .
The number of slips that are marked other than is,
.
The probability of slips that are marked other than is,
.
The probability that slip is marked other than is .
Hence, option 2) is correct.
