76. Exemplar Exercise Problem XXXV

Box A contains $25$ slips of which $19$ are marked $₹1$ and other are marked $₹5$ each. Box B contains $₹50$ slips of which $₹45$ are marked $₹1$ each and others are marked $₹13$ each. Slips of both boxes are poured into a third box and resuffled. A slip is drawn at random. What is the probability that it is marked other than $₹1$?

 

The probability that it is marked other than $₹1$ is $\frac{i}{i}$.
