Solve the following problems by using the binomial formula. a. If n=4 and p = 0.35, find Plx = 3). b. If n = 7 and p = 0.85, find P[x = 4). c. If n=10 and p = 0.55, find Plx 27). d. If n= 12 and p = 0.40, find P(5 sxs 7). (Round the intermediate values to 4 decimal places. Round your answers to 4 decimal places, eg. 0.2153.) a. P(x + 3) = b. P(x + 4) = c. Plx 27) d. P(5 sxs 7)
