Compute​ P(X) using the binomial probability formula. Then determine whether the normal distribution can be used to estimate this probability. If​ so, approximate​ P(X) using the normal distribution and compare the result with the exact probability. n=50​, p=0.50​, and x=17 For n=50​, p=0.5​, and X=17​, use the binomial probability formula to find​ P(X). Q: By how much do the exact and approximated probabilities​ differ? A. ____​(Round to four decimal places as​ needed.) B. The normal distribution cannot be used.
