Consider the probability that at least 93 out of 154 CDs will not be defective. Assume the probability that a given CD will not
be defective is 61%.
Approximate the probability using the normal distribution. Round your answer to four decimal places.

Answer:
0.5962
Step-by-step explanation:
Given that :
p = 61% = 0.61
q = 1 - p = 1 - 0.61 = 0.39
n = 154 ; x = 93
Using the binomial probability formula :
P(x =x) = nCx * p^x * (1 - p)^(n - x)
P(x>=93) = p(x=93)+p(x=94)+...+p(x=n)
P(x>= 93) = 0.59619
P(x>= 93) = 0.5962

=> 1/256
Hey there!
63 = 13 + 2P subtract 13 from both sides
50 = 2P divide both sides by 2
25 = P
So the cost of one pass = $25

Answer:
35
Step-by-step explanation:
M=5J
J=M/5
42=6J
42/6=7
Jullian is 7
7x5=35
Mary is 35
35+7=42
Density = mass / volume
volume of 1 can = 12 * 40 = 480 cm^3
1.1 = mass / 480
mass = 528 grams Answer
