A survey of 500 farmers showed that of the farmers, 26 grew only wheat, 114 grew only corn, 93 grew only oats, 211 grew wheat, 68 grew wheat and corn, 56 grew wheat and oats, and 194 grew corn. Determine the number of farmers who a) grew at least one of the three, b) grew all three, c) did not grow any of the three, and d) grew exactly two of the three. This is an application of sets problem with a venn diagram. I don't know how to do the venn diagram backwards or how to do the math. Please help

Show All Work Please... Consider a deck of cards that has 80 cards. Of these, 60 have a color and 20 are “wild.” The 60 cards with a color are either red, yellow, green, or blue, with 15 of each color. Two cards are said to “match” if any of the following are true: they have the same color, one is a color and the other is wild, or both are wild. (This is a simplified version of the card game UNO.) Two cards are drawn from the well-shuffled deck without replacement. Express your answers to (a)-(d) as simplified fractions or as percentages rounded to the nearest hundredth of a percent. (a) What is the chance that both are blue? _________ (b) What is the chance that both are color cards and they are the same color? _________ (c) What is the chance that one is a color card and the other is wild? _________ (d) What is the chance that they match, using the definition above? _________ (e) Are the following two events mutually…
Suppose I have 6 nieces and nephews (total, not six of each!) and I have just won a set of 8 CD's. In how many different ways can I: a) Give each child a CD? b) Give away all the CD's so that each child gets at least one (hint: try c first)? c) Give away all the CD's so that each child gets at least one without giving any child more than two?

Television and radio stations use four call letters starting with W or K, such as WXYZ or KRLD. Assuming no repetitions in the second to fourth letters, how many four-letter sets are possible using either W or K and only the letters A to P? (Count all possibilities even though, practically, some may be inappropriate.)
