The smallest number which is considered a usual value for the Random Variable can be found by "Mean - 2*standard deviation". The largest number which is considered a usual value for the Random Variable can be found by "Mean + 2*standard deviation" If X is a binomial random variable which gives the number of correct answers on a test, where there are 149 questions, and each question has 5 possible responses. (of which exactly one is correct). Find the smallest value that would be considered usual for X (write as a decimal).
