And insurance agent receives 15% of the cost of each insurance policy she sells how much does the agent receive for a policy ths
hammer [34]

In this question there are several important information's provided. Using these information's it is easy to get the answer to the question asked. Firstly it is already informed that the insurance agent gets a commission of 15% of the policy price for every policy sold. The agent sells a policy of $300.

Now we can write the equation as:

15% of $300 = [(15/100) * 300] dollars

                    = ( 15 * 3) dollars

                    = 45 dollars

So the agent gets a commission of $45 for selling a policy worth $300

P (A or B ). P(A or B) indicates​ _______. Choose the correct answer below. A. the probability that A and B both occur in the sa
Leokris [45]

Answer:

Option B is right

Step-by-step explanation:

P(A or B)

In set theory if A and B are two sets we have either A occurs or B occurs or both as

P(A or B) = P(AUB)

This implies that A occurs or B occurs

Probability is calculated as P(A)+P(B)-P(AB)

P(AB) here represents both occurring and this is subtracted as this was added two times

Option A is wrong because this is AB

Option C is wrong because it is not necessary A occurs first

D is wrong because this is A'UB' where A' represents the complement of A

So correct answer out of four options is

B. the probability that in a single​ trial, event A​ occurs, event B​ occurs, or they both occur.
