Find the probability of no successes in six trials of a binomial experiment in which the probability of success is 30% Round to the nearest tenth of a percent.

Answer 1

an easy way to look at this is that for there to be no successes we would have to fail 6 times in a row

If prob of success is .3 the prob of failure is .7

prob of 6 failures is .7 raised to the 6th power .117649.

or 11.7649%. rounded to 11.8%
