Since you make no other restrictions, the numbers can have duplicates.
9 + 9 + 2 is one possibility.
9 + 7 + 4 is another

Answer:
The answer is "0.03125".
Step-by-step explanation:
Two types of undergraduates exist. Its chance for selecting the very first person who is part of degree studies will be 1/2. The probability will also be 1/2 for the 2nd person, as well as, the 3rd, 4th, and 5th person. For 5 random samples, the probability of the graduate therefore is

Answer:
23 students expected to have scores greater than 60.
Step-by-step explanation:
60 is 2 standard deviations above the mean. This translates into a z-score of +2. According to a table of z-scores, the area under the standard normal curve to the left of z = 2 is 0.9772; that to the right of z = 2 is 1.0000 - 0.9772, or 0.0228. This 0.0228 represents the probability that a given score is greater than 60.
This fraction (0.0228) of 1000 students comes out to 23 (rounded up from 22.75).
