Answer

He should've drawn the arrow starting from -15 pointing right to show how adding these two numbers would equal zero... hope this helped

Answer:

The first arrow was correct starting at zero moving 15 units to the left representing -15.

The second arrow should start at -15 and got to the right 15 Units ending at 0 which represents +15.

-15+15 = 0

A fast-food company is interested in knowing the probability of whether a customer viewed an advertisement for their new special
lord [1]

Answer:

45% probability that a randomly selected customer saw the advertisement on the internet or on television

Step-by-step explanation:

We solve this problem building the Venn's diagram of these probabilities.

I am going to say that:

A is the probability that a customer saw the advertisement on the internet.

B is the probability that a customer saw the advertisement on television.

We have that:

A = a + (A \cap B)

In which a is the probability that a customer saw the advertisement on the internet but not on television and A \cap B is the probability that the customers saw the advertisement in both the internet and on television.

By the same logic, we have that:

B = b + (A \cap B)

12% saw it on both the internet and on television.

This means that A \cap B = 0.12

20% saw it on television

This means that B = 0.2

37% of customers saw the advertisement on the internet

This means that A = 0.37

What is the probability that a randomly selected customer saw the advertisement on the internet or on television

A \cup B = A + B - (A \cap B) = 0.37 + 0.2 - 0.12 = 0.45

45% probability that a randomly selected customer saw the advertisement on the internet or on television
