Assume a normal distribution and find the following probabilities. (Round the values of z to 2 decimal places. Round your answers to 4 decimal places.)

(a) P(x < 21 | μ = 23 and σ = 3) enter the probability of fewer than 21 outcomes if the mean is 23 and the standard deviation is 3

(b) P(x ≥ 75 | μ = 60 and σ = 9) enter the probability of 75 or more outcomes if the mean is 60 and the standard deviation is 9

(c) P(x > 54 | μ = 60 and σ = 5) enter the probability of more than 54 outcomes if the mean is 60 and the standard deviation is 5

(d) P(19 < x < 24 | μ = 21 and σ = 3) enter the probability of more than 19 and fewer than 24 outcomes if the mean is 21 and the standard deviation is 3

(e) P(x ≥ 104 | μ = 90 and σ = 2.76) enter the probability of 104 or more outcomes if the mean is 90 and the standard deviation is 2.76
