Answer:
0.60.6
Step-by-step explanation:
AA and BB probability is 0.60.6.
B. has the lowest value because A. = 89 B. = -109 C. = 37 and D. = 20
Answer:
c=35
Step-by-step explanation:
c=180-d
c=180-145
c=35
Let A represents the event that DVD has a video effect.
So,
P(A) = 1.5 %
Let B represents the event that DVD has a audio defect.
So,
P(B) = 0.8 %
A ∩ B represents that DVD has both audio and video defect.
So,
P(A∩B) = 0.4%
Part a)
A ∪ B represents that DVD has a video or audio defect.
P(A∪B) = P(A)+P(B)-P(A∩B) = 1.5 + 0.8 - 0.4 = 1.9%
Thus the probability that the DVD purchased by the customer has a video or audio defect is 1.9%.
Part b)
The complement of P(A∩B) will represent the probability that the DVD does not have video or audio defect.
So, the probability that DVD purchased by customer does not have video or audio defect is 1 - 0.4 = 0.96%
35/8 = (4 * 8 = 32) and 3 left over so answer is 4 3/8
