NEED HELP WITH PART D ONLY!(At least 10 ties are not too tight) A research team conducted a study showing that approximately 15% of all businessmen who wear ties wear them so tightly that they actually reduce blood flow to the brain, diminishing cerebralfunctions. At a board meeting of 15 businessmen, all of whom wear ties, what are the following probabilities? (Round your answers to five decimal places.)USE SALT(a) at least one tie is too tight(b) more than three ties are too tight(c) no tie is too tight(d) at least 10 ties are not too tight

Given that n=15, q=15%=0.15, p=1-0.15=0.85 X~Binomial(n=15, p=0.85) X be the number of tie too not…
