Answer: 1</h3>
Work Shown:
P(A or B) = P(A) + P(B) - P(A and B)
P(A or B) = 0.8 + 0.55 - 0.35
P(A or B) = 1.35 - 0.35
P(A or B) = 1
A probability of 1 means there is 100% certainty the event happens. This must mean that there are only possible outcomes are: either event A happens, or B happens, or possibly both A and B happen simultaneously.
Answer:
40cm
Step-by-step explanation:
Given data
Length= 15cm
Width=30cm
Volume= 18liters
1000cm^3= 18liters
18000cm^3= 18liters
We know that volume
Volume= L*W*h
18000= 15*30*h
18000=450h
h= 18000/450
h= 40cm
Hence the height is 40cm

Answer:
Step-by-step explanation:
perimeter is the sun of all sides, so, (x)+(x+3)+(x-4)+(2x)
= x+x+3+x-4+2x
= 5x-1 is the answer
