- 6- IfX~N(7,4), the P(15.364 < (X-7)2 20.095) is5 (23 — 2) (2а? — аг)* dar5. Which number is less? (110) - (10) (100) - (10) (100) or = (10) (108) ? 2 Notice that 110 100+10 so we can treat the first number as the number of ways to pick 4 out of 110 people, but at least two of them should belong to the distinuished group of 10. The other number stands for the choice of 2 people out of the distinguished group of 10 out of 110, and then adding another 2 out of remainging 108 to this group. So which number is less?
