Answer:
a. P(A) = P(B)
c. P(A) = 1 - P(B)
a and c are true . The rest are false.
Step-by-step explanation:
Two events A and B are said to be <u>equally likely </u> when one event is as likely to occur as the other. In other words each event should occur in equal number in repeated trials. For example when a fair coin is tossed the head is likely to appear as the tail, and the proportion of times each side is expected to appear is 1/2.
So when the events A= {1,3,4} B = {2,4,5} are equally likely then suppose their probability is 1/2.
a. P(A) = P(B) <u>True</u>
1/2= 1/2
b. P(A) = 2P(B) <u>False</u>
<u>1/2 is not equal to 1</u>
c. P(A) = 1 - P(B) <u> True</u>
1/2= 1-1/2= 1/2
d. P(A) + P(B) > 1 False
1/2 + 1/2 is not greater than 1
e. P(A) - P(B) < 0 False
1/2-1/2= 0 is not less than 0
f. P(A) - P(B) > 1 False
1/2-1/2= 0 is not greater than 1

Answer:
Area of the rectangular doormat = 2/5 m²
Step-by-step explanation:
Length of the rectangular doormat = 4/5m
Width of the rectangular doormat = 1/2m
What is the area of the doormat?
Area of a rectangle = length × width
= 4/5m × 1/2m
= (4×1) / (5×2)
= 4 / 10
= 2/5 m²
Area of the rectangular doormat = 2/5 m²

Step-by-step explanation:
The least intense sound a human ear can hear ,
The sound intensity level that Brandon can hear ,I= 
The sound intensity level of the mower that Ahmad ,I'=
So, the:
The the loudness heard by the mower will be 4 times the loudness heard by the Brandon.
