Find the probability that in a random arrangement of the letters of the word тАШSOCIALтАЩ vowels come together



Answer -

Given: The wordтАШSOCIALтАЩ.

By using the formula,

P (E) = favourableoutcomes / total possible outcomes

In the randomarrangement of the alphabets of word тАЬSOCIALтАЭ we have to find the probabilitythat vowels come together.

Total possibleoutcomes of arranging the alphabets are 6!

n (S) = 6!

Let E be the eventthat vowels come together

Number of vowels inSOCIAL is A, I, O

So, number of ways toarrange them where, (A, I, O) come together

n (E) = 4! ├Ч 3!

P (E) = n (E) / n (S)

= [4! ├Ч 3!] / 6!

= 1/5
