A particular lake is known to be one of the best places to catch a certain type of fish. In this table, x = number of fish caught in a 6-hour period. The percentage data are the percentages of fishermen who caught x fish in a 6-hour period while fishing from shore. x 0 =45% 1 = 43% 2=15% 3= 5% 4 or more = 1% (a) Convert the percentages to probabilities and make a histogram of the probability distribution....
