Suppose that a random variable Z has a standard normal distribution. Use a standard normal table such as this one to determine the probability that Z is between –1.67 and 1.33. Give your answer in decimal form, precise to at least three decimal places. P(-1.67 < Z < 1.33) = w​

Consider a bag that contains 220 coins of which 6 are rare indian pennies. for the given pair of events a and b, complete parts (a) and (b) below. a: when one of the 220 coins is randomly selected, it is one of the 6 indian pennies. b: when another one of the 220 coins is randomly selected (with replacement), it is also one of the 6 indian pennies. a. determine whether events a and b are independent or dependent. b. find p(a and b), the probability that events a and b both occur.
