supplier 2 25 5
3 30 10
Let A denote the event that a sample is from supplier 1, and let B denote the event that a sample from any supplier conforms to specifications. If a disk is selected at random, determine the following probabilities.
Input your answers in the fractional form (do not simplify).
P(A)=0.3
P(B)=0.77
P(A Intersection B) =0.22
P(A U B)=0.85
PLS HELP FIND P(A' U B)?
