Answer:

Step-by-step explanation:
- The probability distribution provides the probabilities of occurrence of different possible outcomes, in this case we want to know what is the probability that the variable X takes any value between 9 and 18.
- The probability of occurrence is shown in the vertical axis of the graph. We want to know what is the probability of finding values of X between 9 and 18, then we should add up the probabilities between these two values , which means adding

Answer:
<em>The quotient will be between 18 and 19.</em>
<em>Estimated quotient will be 18.75</em>
Step-by-step explanation:
The closest number to 75 which is divisible by 4 and <u>less than 75</u> is : 72 and
the closest number to 75 which is divisible by 4 and <u>greater than 75</u> is : 76
Now,
and 
That means, the quotient for
will be between 18 and 19.
As, 75 is 1 less than 76, so the quotient will be
or
less than 19.
So, the quotient will be:
