When you say "I want to make sure that I solved them correctly,
the tasteful, less suspicious thing to do is to list YOUR solutions,
so that the responder can either say "that one's correct" or else
show you how to do it.

a). The probability of each one is 1/8 = 12.5% .
b). There's only one of those on the list. 12.5%
c). 12.5%
d). There are 3 ways that can happen. 3/8 = 0.375 = 37.5%
2). There are 16 possible outcomes.
a). Prob of each outcome is 1/16 = 0.0625 = 6.25% .
b). There's only 1 way that can happen, so it's 6.25% .
c). There's only 1 way that can happen, so it's 6.25% .
d). There are 6 ways that can happen. Prob = 6/16 = 37.5%
e). There are 4 ways that can happen. Prob = 4/16 = 25%
Make a 4x4 table where rows are Alice, Bart, Pamela, and Robert, and where columns are the professions: Dentist, Laywer, Teacher and Writer.
Start crossing out possible pairing person-profession using the facts given. When a job is clearly assigned, you can cross it off for the rest of the people, for example, Pamela is a dentist so none of the rest are a dentist (because we are told they have all different jobs).
Eventually your table becomes filled.
Alice is a Lawyer
Bart is a Writer <<< so this is choice (B) for your answer
Pamela is a Dentist
Robert is a Teacher

Answer:
The out-of-state tuition would be $8800.
Step-by-step explanation:
Given that:
The ratio of in-state tuition to out-state tuition = 3:11
If the tuition of in-state is $2400.
Let,
x represent the number of out-of-state tuition.
As the relation is directly proportional.
3 : 11 :: 2400 : x
Product of mean = Product of extreme
11*2400 = 3x
3x = 26400
Dividing both sides by 3
Hence,
The out-of-state tuition would be $8800.
Answer:
45 !!
Step-by-step explanation:
Anne = 5x
Dawn= 3x
Amount = 120
5x + 3x = 120
8x = 120
x= 120/8 = 15
Anne = 5x = 15 x 5 = 75
Dawn= 3x = 15 x 3 = 45
I hope im right!!
