Using conditional probability, it is found that there is a 0.12 = 12% probability that a student gets an A in Algebra 2 and does all their assignments.
<h3>What is Conditional Probability?</h3>
Conditional probability is the probability of one event happening, considering a <u>previous event</u>. The formula is:
In which
- P(B|A) is the probability of event B happening, given that A happened.
- is the probability of both A and B happening.
- P(A) is the probability of A happening.
In this problem, the events are:
- Event A: Student gets an A in Algebra 2.
- Event B: Student completes all the assignments in Algebra 2.
The probabilities are:
- The probability that a student gets an A in Algebra 2 is 0.2, hence .
- The probability that a student completes all the assignments in a Algebra 2 is 0.5, hence .
- The probability that a student does all their assignments given that they get an A in Algebra 2 is 0.6, hence .
We want to find , hence:
0.12 = 12% probability that a student gets an A in Algebra 2 and does all their assignments.

Answer: correct choice is B
Answer:
6.74
Step-by-step explanation:
To be able to do these equations, you draw a line down the middle of the equal sign to separate sides. So you are trying to get the variable (m) on one side by itself. In order to do that, you have to move 10.20 to the other side. But whenever you move things to the other side you have to do the opposite in this case it would be subtraction because 10.20 is a positive number but the opposite of positive is negative which means subtraction. So you do
3.46-10.20 which will give you -6.47 and now you have -m left but whenever u have a negative sign in front of a variable that means there is a one beside it. A number besides a variable is multiplication but the opposite is division so we would divide.
-6.47/-1 which is 6.47 :)
