Answer:
0.4833
Step-by-step explanation:
We want GIVEN THAT 200 pages or MORE AND RETURNED ON TIME.
Returned on time
fewer than 200 pages—— 78
200 pages ir more ——116
Returned late
Fewer than 200 pages ——15
Returned late ——31
The first table is returned on time and last row is 200 pages or more, so we take that value "116".
To get probability, we also need the total. We add up all those 4 values:
78 + 116 + 15 + 31 = 240
Thus, probability is = 116/240 = 0.4833
Answer:
y = 12
Step-by-step explanation:
Given
Green = 28
Red = 35
Yellow = y
Prediction of yellow = 16 of 100
Required
Determine y
First, we need to calculate the probability of yellow.
Probability of yellow =
Probability = Yellow/Total
Where
Total = Yellow + Red + Green
Total = y + 35 + 28
Total = y + 63
So,
Probability = y/(y + 63)
Also, the prediction of yellow is 16 out of 100.
Represent this as probability.
Probability = 16/100
Equate both expressions to solve for y
y/(y + 63) = 16/100
y/(y + 63) = 0.16
Multiply both sides by (y + 63)
y = 0.16(y + 63(
y = 0.16y + 10.08
Collect like terms
y - 0.16y = 10.08
0.84y = 10.08
Solve for y
y = 10.08/0.84
y = 12
First, you would multiply .37 and 58. That will give you the percentage.
What do you mean? Pie is 3.14...
