- mean = sum x*p(x)
variance = sum(x-mean)^2*p(x) - a. p(3)=(6C3)(2C0) / (8C3)
b. 1-p(3) - p(x<5|m=2)
- a. p(0), p(1), p(2), p(3)
b. 1-p(0) - Let n = 34, and π = 29/34 = 0.8529
- z1 = cost-mean / standard deviation
z2 = cost-mean / standard deviation - a. z=1.50
b. -.50
c. .5 – part b - Find P(X < 5 )
- a. P (x ≥ 30), find the mean and standard deviation first
b. P (x ≤ 40)
c. P (30 ≤ x ≤ 40) - a. multiply the mission times the probability of disaster
b. P (x ≥ 1), find the mean and standard deviation first
