Question

each individual letter of the word "ACCOMMODATION" is written in a piece of paper and all 13 pieces of paper are placed in a jar, if one piece of paper is selected at random from the jar, find the probability that (i) tje letter 'A' or 'O' is selected, (ii) the letter 'M' or 'C' is selected​

Answer 1

Since the total number of letter in the word is 13,

I) If we count the number of ‘A’s’ in the word, the answer would come as 2,

Knowing that Probability = Number of same letters/Total number of letters,
We can say that the probability of getting ‘A’ is 2/13,

For ‘O’ it would be 3/13.

II) Same rules apply here, both of them are 2/13 and 2/13 respectively.

Hoped my answer helped you!
