Determine the probability P1 for a binomial experiment with =n10 trials and the success probability =p0.1. Then find the mean, variance, and standard deviation. 1)Determine the probability P1. Round the answer to at least three decimal places.
2)Find the mean. If necessary, round the answer to two decimal places.
3)Find the variance and standard deviation. If necessary, round the variance to two decimal places and standard deviation to at least three decimal places.

At the olympic games, many events have several rounds of competition. one of these events is the men's 100-meter backstroke. the upper dot plot shows the times (in seconds) of the top 8 finishers in the final round of the 2012 olympics. the lower dot plot shows the times of the same 8 swimmers, but in the semifinal round. which pieces of information can be gathered from these dot plots? (remember that lower swim times are faster.) choose all answers that apply: a: the swimmers had faster times on average in the final round. b: the times in the final round vary noticeably more than the times in the semifinal round. c: none of the above.
