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
supplier
1 22 8
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 conforms to specifications.
(a) find p(a)
(b) find p(b)
(c) find p(b∣a)
(d) find p(a∪b)
(e) are a and 8 independent? justify your answer.

both the histogram and the stem and leaf plot will visually show how many shoppers were of various ages within each range of data.   the histogram does not give us the specific ages of these shoppers unlike the stem and leaf plot.a histogram does not give us a true range of the data because we do not know exactly how old the shoppers were. a stem and leaf plot will give exact ages, so we can determine the exact range along with all measures of center and the others measures of center.   with the histogram, we cannot find any of these.
