Total marbles in the bag = 15
Red marbles in the bag = 5
Probability of picking a red marble the first time = 5/15 .
If you put it back, then everything goes back to the beginning.
Probability of picking a red marble the second time = 5/15 .
If you put it back, then everything goes back to the beginning.
Probability of picking a red marble the third time = 5/15 .
If you put it back, then everything goes back to the beginning.
Probability of picking a red marble the fourth time = 5/15 .
If you put it back, then everything goes back to the beginning.

Probability of picking a red marble the 20th time = 5/15 .
If you put it back, then everything goes back to the beginning.

Probability of picking a red marble the ' Nth ' time = 5/15 .
If you put it back, then everything goes back to the beginning.
Probability of picking a red marble ' N ' times in a row = (5/15)^N.
Probability of picking a red marble 3 times in a row = (5/15) (5/15) (5/15).
Probability of picking a red marble 2 times in a row = (5/15) x (5/15)
= (25/225) = 1/9
= 11.1% (rounded).
Answer:
(C.)
Step-by-step explanation:
Answer:
7-10. domain is all x, range is all y
11. just name all numbers other than 6, 8, and 10 (1, 2, 7, etc.)
12a. (-1,0), (-2,-1), (0,1) (1,2)
12b. Yes, none of the domains are the same and the ordered pairs listed above all follow the rules stated. If it did not follow the rules, the pair(s) would not be Relation B
Step-by-step explanation:
11: In order for relations to be functions, the "x" of the pair needs to be different from the rest. Having the same "x" as another ordered pair would not make it a function.
12a. Follow the rules they state, x ==> y (which I think means x is the number before y) and y > x, honestly not even sure if this is correct
12b. If x ==> was correct in my interpretation, then the ordered pairs I listed should all fit within the boundaries of what relation B would be defined as.
