Answer:
0.0713 = 7.13% probability that the result is positive.
Step-by-step explanation:
Probability of a positive test:
91% of 1/650(has the disease).
7% of 1 - 1/650 = 649/650(does not have the disease). So
0.0713 = 7.13% probability that the result is positive.
Answer:
P (Even number) = 1/2
P(spinner will land on an odd number) = 1/2
P(spinner will not land on 2 or 3) = 3/4
P(spinner will not land on a multiple of 3) = 3/4
Step-by-step explanation:
Here, while spinning the spinner total possible outcomes
are 8 = {1,2,3,4,5,6,7,8}
Now,
a) E: Probability of getting even number
Favorable outcomes are {2,4,6,8}
Hence,
b)E: Probability that the spinner will land on an odd number.
Favorable outcomes are {1,3,5,7}
Hence,
c) E: Probability that the spinner will not land on 2 or 3
Favorable outcomes are {1, 4,5,6,7,8}
Hence,
d) E: Probability that the spinner will not land on a multiple of 3
Favorable outcomes are {1,2,4,5,7,8}
Hence,
