Complete Question:
The conditional relative frequency table was generated using data that compared the cost of one ticket for a performance and the method by which the ticket was purchased.
Given that Lorenzo paid more than $30 for a ticket, what is the probability that he purchased the ticket at the box office? Express the answer in decimal form
Answer:
0.14
Step-by-step explanation:
From the attached diagram, we were given a table that contained known values:
The number of tickets that were purchased online we have 2 categories
a) Not more than $30 = 0.7
b) More than $30 = 0.86
The number of tickets that were purchased at the box office also had 2 categories.
a) Not more than $30 = 0.3
b) More than $30 = 0.14
The probability that the ticket Lorenzo paid more than $30 for was purchased at the box office
= P( more than $30 at the box office)
= 0.14
Answer:
a) the temperature is y = 16° C at 9 AM.
b) The probability of selecting 2 vowels at the same time is 2.8%
Step-by-step explanation:
a)
Temperature = y=?
Time = x = 9 A.M
The given equation is:
Putting x = 9 and solving
So, the temperature is y = 16° C at 9 AM.
b)
WORD CLEMSON
Total Words = 7
Vowels = e, o = 2
Probability of selecting 2 vowels at the same time = P(2 Vowels) =?
We will use the formula of combinations nCr = n! / r! (n-r)!
As we are selecting three letter out of 7, the sample space will be 7C3
And
As there are only two vowels in the given word, and we have to find the probability of selecting two vowels so our event space will be 2C2.
P(2 Vowels) = 2C2 / 7C3
= 1/35
= 0.028 = 2.8%
So, The probability of selecting 2 vowels at the same time is 2.8%
