Answer:
-2
Step-by-step explanation:
So we want to find the value of:
Simply add:
Thus, drop the word SUM on -2.
Further notes:
To use the number line to solve, first start by placing your point on -6.
Since we are <em>adding</em> 4 to -6, we move to the right. Thus, move from -6 four spaces to the right.
If you do so correctly, you will end up at -2, the same answer we acquired previously.
Answer:
0.0667 = 6.67% probability that the shares of a company that fires its CEO will increase by more than 5%.
Step-by-step explanation:
Conditional Probability
We use the conditional probability formula to solve this question. It 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:
Event A: Company fires the CEO
Event B: Shares increase by more than 5%.
Probability of a company firing it's CEO:
35% of 100 - 4 = 96%(shares did not increase by more than 5%).
60% of 4%(shared did increase by more than 5%).
So
Intersection of events A and B:
Fires the CEO and shared increased by more than 5%, is 60% of 4%. So
Probability that the shares of a company that fires its CEO will increase by more than 5%.
0.0667 = 6.67% probability that the shares of a company that fires its CEO will increase by more than 5%.
