would like an explanation so i can better understand:) (box answer is would or would not)

6. [-/2.03 Points] DETAILS PECKSTAT2 6.E.044.S. MY NOTES Suppose that the distribution of typing speed in words per minute (wpm) for experienced typists using a new type of split keyboard can be approximated by a normal curve with mean 60 wpm and standard deviation 15 wpm.+ (You may need to use a table. Round your answers to four decimal places.) LO USE SALT (a) What is the probability that a randomly selected typist's speed is at most 60 wpm? What is the probability that a randomly selected typist's speed is less than 60 wpm? (b) What is the probability that a randomly selected typist's speed is between 30 and 75 wpm? (c) Would you be surprised to find a typist in this population whose speed exceeded 105 wpm? It ---Select--- @ be surprising to find a typist in this population whose speed exceeded 105 wom because the probability of finding such a typist is only (d) Suppose that two typists are independently selected. What is the probability that both their speeds exceed 90 wpm? (e) Suppose that special training is to be made available to the slowest 15% of the typists. What typing speeds (in wpm) would qualify Individuals for this training? (Hint: See Example 6.23.) Any typist with a typing speed of wpm or less is in the slowest 15% of typists
