Question
What is the probability that three S’s come
consecutively in the word ‘SUCCESSION’?Solution
Total number of words that can be formed from the letters of the word SUCCESSION = 10!/(3! ×2!) = 302400 When all the S’s are together then the number of words can be formed = 8!/2! = 20160 Required Probability =  20160/302400 = 1/15
