shows a sample of small motors that was inspected and classified into sets A, B and C. There were 8 small motors that were classified as having none of the defects as described in events A, B and C. A randomly picked set of six objects out of this sample of objects is made: A) What is the probability that (WITPT) at least two of the six objects have defects? B) What is the probability that (WITPT) at least 3 of the objects have at least two defects? C) WITPT exactly three of the six objects have shaft size that is not too large but has windings that are improper? 7/2 1 5 B 4 3 6 D) WITPT the last object picked is the only one without defects? E) WITPT the last object picked is the second with at exactly two defects?

Transcribed Image Text:A manufacturer of small motors is concerned with three major types of defects: If A is the
event that the shaft size is too large, B is the event that the windings are improper and C is
the event that the electrical connections are unsatisfactory, the following Venn diagram
