A die is rolled 3 times, and success is rolling a 1. (a) Construct the binomial distribution that describes this experiment, with x indicating the number of successes. (Enter your probabilities as fractions.) (b) Find the mean of this distribution. (Enter an exact number as an integer, fraction, or decimal.) (c) Find the standard deviation of this distribution. (Round your answer to three decimal places.)

Heed help with c only.
(1 point) You are to roll a fair die n = 108 times, each time observing if the topside of the die shows a 6 (success) or not (failure). After observing the n = 108 tosses, you are to count the number of times the topside showed a 6. This count is represented by the random variable X. A. with a mean 18 and a standard deviation 3.87 !! . (a) The distribution of X...
