The correct answers are:
(1) If EXACT number is required, then 7.5.
(2) If multiple of 8 is required then the answer will be 7 times with a remainder of 4.
Explanation:
First you need to express it in the form of equation to make things simpler as follows:
8 * y = 60
We need to find y; to do so, divide 60 by 8:
y =
y = 7.5
Now if you want to find the whole number, then the answer will be 7 times, with 4 left over.
Answer:
The probability of selecting a person which is self-employed but not married equals 1/8.
Step-by-step explanation:
Here, the given survey says:
Total number of people surveyed = 248
Number of people married = 156
The number of people are self employed = 70
Now, 25% of people who are married are SELF EMPLOYED.
Now, calculating 25% of 156 , we get:
⇒ out of total 156 married people, 39 are self employed.
So, number of self employed people but not married
= Self employed people - Self employed people PLUS married
= 70 - 39 = 31.
So, the probability that the person selected will be self-employed but not married = =
Hence The probability of selecting a person which is self-employed but not married equals 1/8.
