The probability that a student has either a vise card or a master card is: 0.72
Step-by-step explanation:
Given that
Probability that a student has a vise card = P(V) = 0.65
Probability that a student has a master card = P(M) = 0.20
Probability that a student has both = P(V∩M) = 0.13
We have to find the probability of V OR M
The probability is given by:
Putting the values,
Hence,
The probability that a student has either a vise card or a master card is: 0.72

Answer:
2 1/4
Step-by-step explanation:
Number 1 is incorrect because 1/4 x 9 is 2 1/4 not 1 1/4.
To multiply fractions, multiply directly across. So multiply 1/4 x 9/1 to get 9/4 which converted into a mixed number is 2 1/4.
You made the choice to choose the letter A, a second time.
Answer:
We have to put the data for purchased item in a frequency table.
Step-by-step explanation:
The diagram is attached below.
Firstly we have to see that how many customers fall under range 
.
Then 
.
Then 
.
Finally
.
If we go through the items purchased by customers we can see that item ranges from have 
customers.
Item purchased range from have 
customers.
Item purchased range from have 
customers.
Item purchased range from have 
customers.
Total number of customers = 
As we have total number of customers and they have varied quantity of items purchased.
Vertical.
the x value its the same for both, so you are going to the same point before moving up or down for the y value.
