Answer:a) 54/55
b) 100/110
c) 99/110
Step-by-step explanation:
a)Probability of ordering 4= 9/12×3/11×2/10×1/9 = 54/11880
Probability of 4 good units= 4 × 54/11880
= 216/11880
1/55
1-(1/55) = 54/55
b)Probability of 2 good units= 2 × 54/(11880)
= 108/11880
= 1/110
1- (1/110)= 100/110
c) Probability of exactly 2 units not good= 1 -(100/110) =99/110

Step-by-step explanation:
Answer:
5.Let Alisha= A
Riley= R
Jordan= J
A=7
R=A+4= 7+4= 11
J=3*7= 21
Riley=11
Jordan=21
6.Red Marbles= 18
Yellow Marbles=18*3=54
Green Marbles=18-10= 8
7.This year= 28 eagles
Last year=28/4 =7 eagles
Difference= 28-7 = 21 Eagles
8.Joel= 8 pictures
Taylor= 8*3= 24 pictures
1 Row= 4 pictures
24 pictures= 24/4= 4 rows
