Explanation:
Detailed explanation-1: -Answer: 5/26. Assuming that only 26 alphabets (a to z) are considered & there are 5 vowels a, e, I, o, u. (Don’t consider y as a vowel). Then probability of selecting vowel from alphabets is 5/26.
Detailed explanation-2: -∴ The probability of choosing a vowel from English alphabet is 5/26.
Detailed explanation-3: -Solution: Given, A E I O U are the cards put facing down. (a) We have to find the chance of drawing out a vowel. Therefore, the chance of drawing out a vowel is 1.
Detailed explanation-4: -Total number of ways in which letters in word “Mathematics” are arranged = 11!/(2! × 2! × 2!) ∴ Probability that vowels are kept together is 4/165.
