In the binomial probability distribution, let the number of trials be 0 = 4, and let the probability of success be p = 0.2878. Use a calculator to compute the following. I use SALT (a) The probability of three successes. (Round your answer to three decimal places.) 0.068 (b) The probability of four successes. (Round your answer to three decimal places.) 0.007 ,f (c) The probability of three or four successes. (Round your answer to three decimal places.) :13
