Q: Given a set of (10) transistors, (2) of them are defective. Choose a sample of (4)
transistors, then
1) find the probability that a sample has:
i-One defective transistors. i-At least one defective transistor.
If X is a random variable represent defective transistors in a sample. Then
2) find the probability function f(x) and distribution function F(x).
3) find (by two methods) the probability that a sample has:
ü-At least one defective transistor.
LOne defective transistors
