Hello from MrBillDoesMath!
Answer:
Choice B
Discussion:
The answer shown highlighted is the correct answer
For a function, each value in the domain should be assigned a unique value in the range. In the case of ordered pairs, each x value in an order pair should have a unique y value. This aspect fails for Choices A, C, and D. Details follow.
Choice A: Not a function because (3,3), and (3,2) both have x = 3 but associated y value is not unique (equal 3 or 2)
Choice C: Not a function because (1,-1) and (1, -2) both have x = 1 but associated y value is not unique (equals -1 or -2)
Choice D: Not a function because (2,3) and (2,1) both have x= 2 but associated y value is not unique (equals 3 or 1)
Choice B has no such issues as an x value is repeated.
Thank you,
MrB

Answer:
P(B) = 0.6
Step-by-step explanation:
P(A and B) = P(A) * P(B)
0.12 = 0.2 * P(B)
P(B) = 0.6
P(A or B) = P(A) + P(B) - P(A and B)
0.68 = 0.2 + P(B) - (0.12)
P(B) = 0.6
