1 A local pottery makes cups. The number of faulty cups made by the pottery in a week follows a Poisson distribution with a mean of 6
In a randomly chosen week, the probability that there will be at least \(x\) faulty cups made is 0.1528
- Find the value of \(x\)
- Use a normal approximation to find the probability that in 6 randomly chosen weeks the total number of faulty cups made is fewer than 32
A week is called a "poor week" if at least \(x\) faulty cups are made, where \(x\) is the value found in part (a).
- Find the probability that in 50 randomly chosen weeks, more than 1 is a "poor week".
