COMPLETE QUESTION:
Chris went on a vacation for a week and asked his brother Paul to feed his old cat Charlie. But Paul is forgetful, and Chris is 70% sure Paul will forget to feed his cat. Without food, Charlie will die with probability 0.5. With food, he will die with probability 0.03. Chris came back from vacation and found Charlie alive. What is the probability that Paul forgot to feed Charlie (round off to third decimal place)?
Answer:
The probability that Paul forgot to feed charlie is 0.546
Step-by-step explanation:
Lets denote F the event 'Paul forgot to feed Charlie', and L the even 'Charlie is alive', we have
P(F) = 0.7
P(L|F) = 1-0.5 = 0.5
P(L|F^c) = 1-P(L^c|F^c) = 1-0.03 = 0.97
We want to calculate P(F|L). We will use Bayesformula at the start and the theoremoftotalprobability to calculate P(L).
Given that Charlie is alive, the probability that Paul forgot to feed charlie is 0.546.
Answer:
P = 0.546
Step-by-step explanation:
Hi,
This is a question of conditional probability, which means to find probability of a situation given that another event has already occured:
In this question, we need to find the probability of Charlie being alive if not fed, with the data given below:
From this data, we can infer the following:
The probability of Charlie staying alive in both cases:
We need to find the probability when not fed:
(Remember this is the variation of the conditional probability formula as per our requirement in this question).
Hence, the probability of Charlie being alive when Paul forgets is 0.546.

The volume of the toy box in cubic feet is 18 ft³.
A prism is a three-dimensional object.
There are triangular prism and rectangular prism.
We have,
First, we need to convert the dimensions of the box from inches to feet:
Height: 24 inches ÷ 12 inches/foot = 2 feet
Width: 36 inches ÷ 12 inches/foot = 3 feet
Length: 36 inches ÷ 12 inches/foot = 3 feet
So, the box has a height of 2 feet, a width of 3 feet, and a length of 3 feet.
To find the volume of the rectangularprism,
We multiply the height by the width by the length:
Volume = 2 feet x 3 feet x 3 feet = 18 cubic feet
Therefore,
The volume of the toy box in cubic feet is 18 ft³.

Answer:
33 in
Step-by-step explanation:
The Pythagorean theorem tells you ...
diagonal² = length² +width²
diagonal² = (16 in)² +(28.5 in)² = 1068.25 in²
diagonal = √(1068.25 in²) ≈ 32.684 in
The diagonal of the television is about 33 inches.

Answer:
18, 19, 20
Step-by-step explanation:
We can have the lowest number be , and the second and third numbers be and . Now we have the equation
x=18, so the numbers are 18, 19, and 20.
