Question
A jar contains six 50 paise coins, six Rs. 1 coins, and
twelve Rs. 10 coins. One coin is lost. Find the probability that the lost coin is not a 50 paise coin.Solution
Number of 50 paise coins = 6
Total number of coins = 6 + 6 + 12 = 24
So, the required probability = 1 - 6/24 = 18/24 = 3/4
564.932 + 849.029 – 425.08 = 612.095 + ?
999.99 + 99.99 + 99= ?
