Homework Statement
The following is a random experiment.
A wafer from a semiconductor manufacturing is to be selected randomly and a location on the wafer inspected for contamination particles. The sample space for the number of contamination particles at the inspected location is S= {0, 1, 2, 3, 4, 5}.
Relative frequencies for these outcomes are 0.4, 0.2, 0.15, 0.10, 0.05 and 0.10 respectively.
Use relative as probabilities.
Let A be the event that there are no contamination particles at the inspected location.
Let B be the event that there are at most three contamination particles at the inspected location.
Let C be the event that there are an odd number of contamination particles at the inspected location.
1- How many events are possible?
2- Find the probability of the following:
-Complement (A )
-B (intersction) C
Homework Equations
Relative probability= n/N
n- number of specific events occured.
N- total number of posiible events
The Attempt at a Solution
for the number of events:
I did 2^3=8 possible event but really I have no confindence in my answer
For question 2 , I dont get it. I have formula but does nos help me much.
Can I have some help from an expert please?
