b) 0.613
c) Part(a)
d) Unusual event
Step-by-step explanation:
We are given the following in the question:
x: 0 1 2 3 4 5 6 7 8
P(x): 0.000 0.003 0.016 0.054 0.121 0.193 0.226 0.193 0.121
x: 9 10 11 12
P(x): 0.054 0.016 0.003 0.000
a) Probability of exactly 6 Mexican-Americans among 12 jurors.
Thus, 0.226 is the probability of exactly 6 Mexican-Americans among 12 jurors
b) Probability of 6 or fewer Mexican-Americans among 12 jurors
Thus, 0.613 is the probability that 6 or fewer Mexican-Americans among 12 jurors.
c) The result from part (a), because it measures the probability of exactly 6
successes.
d) Unusual event
An event is said to be unusual if the probability of event is less than 0.5.
Since
Thus, it is an unusual event as the probability is less than 0.5
Answer:The number of words that she would still have to type to finish her essay is 1000
Step-by-step explanation:
Karen is typing a 4,000 word essay. She can type at about 30 words per minute. This means that if her rate remains constant, the total number of minutes that it will take her to finish would be
4000/30 = 133.33 minutes.
If she types for 45 minutes on Monday, it means that the total number of words that she typed on Monday would be
45 × 30 = 1350 words
If she types for 55 minutes on Tuesday, it means that the total number of words that she typed on Tuesday would be
55 × 30 = 1650 words
Total number of words typed on Monday and Tuesday would be
1350 + 1650 = 3000 words
The number of words that she would still have to type to finish her essay would be
4000 - 3000 = 1000 words
