x=58.67
Answer:
there is a 1 in 14 chance of getting 14 and there is a 11 in 14 chance of getting a number less than 12.
Step-by-step explanation:
since there are 14 numbers, there is only one 14, so that means 1 in 14 chance. that can be written as 1:14 or 1/14. there are 14 #and 11 less than 14 so 11:14 or 11/14. unless you mean 12 or less, because then its 12/14. unless you leave the first number you drew out, then it would change to 11/13 or 12/13
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%
