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 1 2 3 4 or more

% 42% 35% 13% 9% 1%

Find the probability that:

-a fisherman selected at random fishing from shore catches one or more fish in a 6-hour period. (Round your answer to two decimal places.) -

- catches two or more fish in a 6-hour period

-he expected value of the number of fish caught per fisherman in a 6-hour period

- the standard deviation of the number of fish caught per fisherman in a 6-hour period
