20. Suppose sets A and B are as follows - A - {a, b, f, g, i} and set B - {a, b, d, f, h } . Find An B O AnB = {a, f } O AnB = {a, b, f} O AnB = {a, f, h} O AnB = {a, b, d, f, g, h, i } O AnB = {a, b, f, h} 21. Use the table below to determine n ( A U E) . C D E Total A 10 13 30 B 22 15 33 70 Total 32 22 46 100 Enter answer here 22. If an unbiased coin is flipped five times, the probability of getting five heads is 1/32. Does this mean that if I flipped five coins 32 times, then exactly one of those 32 times I would get five heads? Yes. No, it means that if five coins were flipped many times about 1/32 nd of the time the result would be two heads No, a probability of 1/32 tells us nothing
