Question 1

A true false test consists of 10 questions

(a) If Ryan does not study at all and guesses each and every question in the test, describe the probability model for the number of correct guesses?

(b) What is the probability Ryan gets 80% overall for the test

(c) If it is a 20 question true/false exam, would it be easier or more difficult for Ryan to get 80% or more? Explain without any calculation

If anyone can help with this question that would be great, thank you

The probability she gets all 50 correct. The probability she gets at most half correct.
