Question
Each card bears one letter from the word ‘mathematics’ The cards are placed on a table upside down. Find the probability that a card drawn bears the letter ‘m’.
Solution
Total number of letters in word 'mathematics' = 11
Number of letters in word 'mathematics' = 2
Therefore, required probability = `"Number of letters m"/"Total number of letters" =2/11`
Hence, the probability that a card drawn bears the letter ‘m’ is `=2/11`.
