Question 1.
Rishabh plays a game with two dice in a fete. He draws three columns on a chart paper. In the left-most column, he writes the digits less than 7 and in the rightmost column he writes the numbers greater than 7. In the middle column, he writes digit 7 only. He offers people to keep money on any one of the columns. He throws two dice together if the sum of the digits on the two dice is less than 7, he doubles the money kept on the left-most column and collect the money kept on the remaining two columns. Similarly, he doubles the money on a rightmost column if the sum of digits is greater than 7 and triples on the middle column if the sum of the digits is 7. What digits should he write on leftmost and rightmost columns?
Is this game a sort of gambling? Is gambling a good way of earning money?
