Find the probability that a randomly selected adult has an IQ greater than 125.0The probability that a randomly chosen student in a statistics class submits his/her homework on time is 0.12. There is 35 student in the class. Each student does his/her homework independently. What is the standard deviation of X, where X is the number of students who submit the homework on time?You play a game of chance in which you can either win or lose (there are no other possibilities). The probability of winning is 0.22. What is the standard deviation of X, where X is the number of times one needs to play a game until one gets the first win?
