The answer is B because 90 to 30 is 3 over 2
Y=my+b so substitute in the corindates to get y !!
Answer: a) No, b) 0.78, c) No.
Step-by-step explanation:
Since we have given that
P(A) = 0.7
P(B) = 0.2
P(A∩B) = 0.12
(a) Are A and B independent? Explain.
Since P(A).P(B) =
And P(A∩B) = 0.12
P(A∩B) ≠ P(A).P(B)
So, they are not independent.
(b) Compute P(A or B).
(c) Are A and B mutually exclusive? Explain
Since P(A∩B) ≠ 0
So, they are not mutually exclusive.
Hence, a) No, b) 0.78, c) No.
Answer:
The answer is B 133 and 135
