Step-by-step explanation:
What is the probability of forming word from the letters of word "impeach" such that all vowels come together?
impeach
total letters = 7
Total number of Words which can be formed = 7! = 5040
All vowels together iea - 3 vowels & 4 consonants
Taking 3 vowels as 1
total = 5
& three vowels can be arranged in 3!
Total words where all vowels come together = 5! * 3! = 720
Probability = 720/5040 = 1/7
