Y=4/3-1/4 I guess. I am not sure for the 1/4
All you have to do is 12 times 4.5 . and that's your answer
Answer:
Step-by-step explanation:
If the number of defects in poured metal follows a Poisson distribution, the probability that x defects occurs is:
Where x is bigger or equal to zero and m is the average. So replacing m by 2, we get that the probability is equal to:
Finally, the probability that there will be at least three defects in a randomly selected cubic millimeter of this metal is equal to:
Where
So, P(0), P(1) and P(2) are equal to:
Finally, and are equal to:
