Answer:
b. 0.45.
Step-by-step explanation:
The total possible outcome of a probability is 1
Given;
Probability that both lights will be red when she reaches them = 0.22
Probability that the first light will be red and the second light will not be red = 0.33
Probability that the second light will be red when she reaches it = x
These are all the possible outcomes, therefore
0.22 + 0.33 + x = 1
0.55 + x = 1
x = 1 - 0.55
x = 0.45
Option b
Answer:
suppose length is x
breadth is y
now,
x.y=18
2(x+y)= 18
x= 3
y=6

Answer:
$22.5
Step-by-step explanation:
2.5% = .025

600 multiplied by .025 = 15
15 divided by .5 = 7.5
15 + 7.5 = 22.5
