three items were randomely selected from a bin that contains 3 defective and 7 non-defective lithium batteries.
--------------------------------------------
let the random variable X represent the number of defective batteries in the sample.
--------------------------------------------
A) what are the possible values of C?
What is "C"?
-------------------------
B) Obtain the PMF pf X.
What is the PMF?
-------------------------
C) Calculate P(X=0) = 7C3/10C3 = 0.2917
-------------------------
D) Calculate P(X is greater than or equal to 1)
Ans: 1- 0.2917 = 0.7083
