Answer:
a)
b)
Step-by-step explanation:
For this case our sample space is the 5 letters given:
And we want to find the number of three letter words can be made from the sample space with some conditions
Part a
For this case the repetition is allowed so then each time we will have 5 possibilites in order to select one letter so if we use combinatories we have:
So then we will have 125 possible combinations of 3 words letters with the 5 provided
We need to remember that
Part b
For this case the repetition is not allowed so then the possible number of possibilities are:
So then we will have 60 possible combinations of 3 words letters with the 5 provided
Answer:
-2 = -3
-1 = 0
0 = 3
1 = 6
Step-by-step explanation:
y = 3(-2)+3
-6+3
-3
y=3(-1)+3
-3+3
0
y=3(0)+3
0+3
3
y=3(1)+3
3+3
6
