Aroom contains 8 people, each of a different age. the people leave the room in random order, one at a time. what is the probability that they leave the room in ascending order of their ages (youngest to oldest)? the probability that they leave the room in ascending order of their ages is nothing.

2.48 × 10⁻⁵

Step-by-step explanation:

Number of people in the room of a different age = 8 people

The number of ways people can leave the room  = 8!

                                                                                 = 40320

They leave the room in ascending order is  = 1 way

The probability they leave the room in ascending order of their ages =

= 2.48 × 10⁻⁵

part a: 850*0.32= 272 people
part b: since 75% is 150, 25% would be 50. so, to get to 100%, you multiply 50 by 4, in that case, there was a total of 200 students
part c: honestly i have no idea :( maybe someone else can help?

part a: since there isn't any number between weighs/pounds, so just multiply that number by 16
part b: 0.14*50=7 gallons --> multiply by 4 to get 28 quarts --> multiply by 2 to get 56 pints

~hope that helps!~
