<h3>What is an event in probability?</h3>
An Event is the set of results from an experiment in probability. Assume you do an experiment by tossing a coin. This experiment results in the coin landing 'heads' or 'tails.' These are the events that are associated with the experiment.
Scenario 1: You are taking a multiple-choice test. Event A is you choose the correct answer. Event B is you choose D as the answer.
The two of the given events will overlap since there is a possibility that the correct answer is option D.
Scenario2: You survey students in your school about what grade they are in. Event A is the person is a senior. Event B is the person who is a junior.
The two of the given events are mutually exclusive events since a person can not be a senior and a junior at the same time.

Answer:
Choice B
Step-by-step explanation:
We can perform a least squares regression model in Ms. Excel to determine the equation of the line of best fit for the data given;
The first step is to enter the data into any two adjacent columns of an excel workbook. Next, click on the Data ribbon followed by the Data Analysis tool pack. We then proceed to select regression from the pop-up window. The final step is to select the y range and the x range of values from our data.
Once we click ok, Excel returns our least squares regression model as shown in the attachment below.
The coefficient of X variable 1 is our slope.
The answer is C. Using ASA postulate, prove that triangles PQS and PRS are similar triangles
It would be 10 using distance formula
Answer:
3.
Step-by-step explanation:
This is an arithmetic sequence with common difference d = 0.5 and first term a1 = -015.
10th term = a1 + (10 - 1)d
= -1.5 + 9*0.5
= 4.5 - 1.5
= 3.
