Suppose that a sample of 100 M&Ms are randomly selected and 27 are found to be blue. Assuming the claimed blue M&Ms rate of 24% is correct, find the probility of randomly selecting 100 M&Ms and getting 27 or more that are blue. Based on your result, is 27 an unusually high number of blue M&Ms when 100 are randomly selected? </SPAN>\n" );
