Answer:
The probability of 4 or fewer unsuccessful plates in one hour is 0.00752.
Step-by-step explanation:
Let <em>X</em> = number of plates that are unsuccessful.
The expected number of unsuccessful plates per hour is, <em>λ</em> = 12.
The random variable <em>X</em> follows a Poisson distribution with parameter <em>λ</em> = 12.
The probability function of a Poisson distribution is:
Compute the probability of 4 or fewer unsuccessful plates in one hour as follows:
P (X ≤ 4) = P (X = 0) + P (X = 1) + P (X = 2) + P (X = 3) + P (X = 4)
Thus, the probability of 4 or fewer unsuccessful plates in one hour is 0.00752.
B because of the 100 5 are in both so 5/100 is .05
Well it would be -5, right? Because you lost (-) $5, you would have a negative five dollars.
