Unformatted text preview: 20 / 36 = 16 / 36 . h. Upon inspection in the sample space, there are nine such outcomes out of 36. Answer is 9 / 36 . 3. The number of distinct ordered triplets with replacement = 7 × 2 × 52 = 728. 4. On the ﬁrst day, there is a choice of 5 pairs, and subsequently, there is a choice of only 4 pairs. Total number is = 5 × 4 × 4 × 4 × 4 × 4 = 5 × 4 5 = 5120. 5. There are 4! = 24 ways in which the four volumes can be put back. Only one of these is correct. P (correct order) = 1 4! = 1 24 . 6. The total number of ways of arranging the word “cold” is 4! = 24. In considering the total number of ways of arranging the word “cool”, the letter “o” is repeated twice, thus 2! arrangements are the same. Thus, total number of ways of arranging the word “cool” is 4! / 2! = 24 / 2 = 12....
