Samples of emissions from three suppliers are classified for conformance to air-quality specifications. The results from 100 samples are summarized as follows: conforms
yes no
1 22 8
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
