Answer:
4 chairs per table
Step-by-step explanation:
Using the binomial distribution, it is found that there is a 0.125 = 12.5% probability of observing exactly 3 tails.
<h3>What is the binomial distribution formula?</h3>
The formula is:


The parameters are:
- x is the number of successes.
- n is the number of trials.
- p is the probability of a success on a single trial.
In this problem, considering 3 tosses of a fair coin, the parameters are n = 3 and p = 0.5.
The probability of 3 tails is P(X = 3), hence:


0.125 = 12.5% probability of observing exactly 3 tails.

Answer:
The answer is B.
Step-by-step explanation:
Given that the fixes amount is $25 per month. In order to find the total cost, C, you have to multiply $25 with the number of months.
C = 25m
As there is no x axis it will have to be vertical as the y axis is already vertical
Start at +1 on the x axis and then use 3/1 for rise over run. So you will start at +1 and then from that point rise 3 run 1
