Hi, I need help with question 2 and 3? How can I figure this out using TI84 calculator? Thank you!

Here is a few scenarios where I want you to describe how you would set up either binomialcdf or binomialpdf on your calculators. Use correct probability notation (ex P(X = 3) = .1314), and for the inequalities give a brief example of which values for X you are trying to "include" in your calculation, and the logic behind why you are setting up your calculator function in a given way. A Multiple Choice test is given consisting of 10 questions, each question having 5 possible answers, one of which is correct. Jimmy hasn't studied and prepared himself for the test, and is therefore forced to completely guess on each question. Find the probability that: (1) He gets exactly 5 (half) of the questions correct (2) He gets ALL the questions correct (3) He gets NONE of the questions correct (4) He gets at least a 60% (passing) on the test. (5) He gets at most 5 correct
