Consider the random experiment of selecting a playing card from a deck of 52 playing cards. each card corresponds to a sample point with a 1/52 probability. how many sample points are there in the event that a king is selected? how many sample points are there in the event that a spade is selected? how many sample points are there in the event that a non face card (non jack, non queen, or non king) is selected? find the probabilities associated with each of the events in parts (a), (b), and (c) (to 2 decimals).

The number of chocolate chips in an 18-ounce bag of chocolate chip cookies is approximately normally distributed with a mean of 1252 chips and standard deviation 129 chips. (a) what is the probability that a randomly selected bag contains between 1100 and 1500 chocolate chips, inclusive? (b) what is the probability that a randomly selected bag contains fewer than 1125 chocolate chips? (c) what proportion of bags contains more than 1225 chocolate chips? (d) what is the percentile rank of a bag that contains 1425 chocolate chips?
