Assume that a set of test scores is normally distributed with a mean of 120 and a standard deviation of 25 Use the68-95-99.7 rule to find the following quantities.

a. The percentage of scores less than 120 is ? %.

(Round to one decimal place asneeded.)

b. The percentage of scores greater than 145 is ?%

(Round to one decimal place asneeded.)

c. The percentage of scores between 70 and 145 ?%

(Round to one decimal place asneeded.)

This exercise involves a complementary event. Find the probability of the given event. Assume that the deck is fair.

Not drawing a 6 from a standard deck of 52 playing cards

The probability of not drawing a 6 is ?%
