You’ve just finished making 3 batches of plastic tumblers: a red batch, a yellow batch, and a purple batch. There are 500 tumble

Answer:

Step-by-step explanation:

Initial Charge = $ 65

Hourly Rate = $ 28

Hours Worked = H

Cost for H hours = 28 * H = 28H

Inequality:

65 + 28H ≤ 250

1/ 816  

Step-by-step explanation:

Step 1 :

Assumptions made

Number of students in the school = 18

Number selected randomly = 3

Step 2 :

Calculating number of ways to choose 3 students from a group of 18:

C(18,3)  = 18! /(3!(18-3)!) =  18*17*16/3*2*1 = 816

Ways to choose the youngest 3 students = 1

Hence, the probability of picking the 3 youngest students from this group is  1/ C(18,3) = 1/ 816
