Answer:73
Step-by-step explanation:
This is the equation
185+185(2)+185-50
185+370+185-50 (you multiply 185 times 2 first)
370+370-50 (you add 185 to 185)
740-50 (you add 370 to 370)
740-50=690

Answer: Probability that a randomly selected unit will contain at least two surface- finish defect is 0.04.
Step-by-step explanation:
Since we have given that
Mean rate defects per unit = 0.3
Since we will use "Poisson distribution":

But we need to find the probability that a randomly selected unit will contain at least two surface-finish defect.

So,

so, it becomes,

Hence, probability that a randomly selected unit will contain at least two surface- finish defect is 0.04.
