Answer:
(a) what is the sample space for this chance process?
If we toss a coin three times then there are total outcomes
The sample space associated with the given chance process is:
(b) what is the assignment of probabilities to outcomes in this sample space?
Since the given sample space has eight outcomes and we know that a fair coin is tosses three times. Therefore, the probability of all the events mentioned in the given sample space is same. Hence we have:
Let's solve your problem:
The answer would be 280%.
We know the following information:
2pm - 15 toilet paper rolls
5pm - 57 toilet paper rolls
We have to find the <u>percent rate of change.</u>
Here is how we will do this problem:
<h3><u>First, Set up a ratio:</u></h3>
Change in the quantity [15 - 57]
-------------------------------------
Original quantity [15]
57 - 15 = 42
<h3><u>Next, we will divide. the ratio.</u></h3>
Given quantity - 42
Number of packs sold at 2pm - 15
Fraction - 42/15
<h3><u>Convert the fraction to a decimal.</u></h3>
Fraction - 42/15
Decimal - 2.8
<h3><u>Make the decimal to a percent.</u></h3>
Decimal - 2.8
Percent - 28%
<u>Add a zero to the 28.</u>
<h2><u>Our answer is 280%</u></h2><h3></h3>
