Answer:
Step-by-step explanation:
This is a binomial probability distribution because the outcome is either a randomly selected first-class mail within the same city is delivered within two days of the time of mailing or more days. The probability of success, p is that it is delivered within 2 days. Therefore,
p = 95/100 = 0.95
q(probability of success) = 1 - p = 1 - 0.95 = 0.05
n = number of samples = 6
1)The probability that all six arrive within two days, P(x = 6) would be determined from the binomial probability distribution calculator. Therefore,
P(x = 6) = 0.74
2) P(x = 5) = 0.23
3) mean = np = 6 × 0.95 = 5.7
4) Variance = npq = 6 × 0.95 × 0.05 = 0.285
Standard deviation = √0.285 = 0.53

Let X = number of minutes.
Plan A = 50 + 0.04X
Plan B = 60 + 0.02X
50 + 0.04X = 60 + 0.02X
Subtract 50 from each side:
0.04X = 10 + 0.02X
Subtract 0.02X from each side:
0.02X = 10
Divide both sides by 0.02
X = 10 / 0.02
X = 500
It will take 500 minutes.
