The 30 students in MATH215A are invited to play “My Deal or NO DEAL!!” Each student will get to select one of 25 cases prior to any being opened. (It’s perfectly acceptable for two or more people to select the same case). After the cases have been selected I, as the host, will start opening the cases one by one eliminating those who didn’t select the case with the $1,000,000. If exactly 4 people selected the million dollar case, everyone will share the spoils. What is the probability that exactly 4 of you will select the correct case?

Write mean and standard deviation of given binominal probability p=.20 and n=100

Binomial probability is one of those subjects that we learn during high school studies, yet good binomial probability examples are not mentioned in most cases, which doesn’t help to solve various questions or find the answers without turning to formulas that do not fit. It’s all about being able to calculate the probability as binomial probability problems can be compared to purchasing a lottery ticket where one can either win or leave without any luck. Addressing the lack of examples, we provide binomial questions and explain how certain answers have been found to address this or that binomial probability equation.
