a. What is the probability that she will get 5questions correct?

I'd appreciate an Excel formula if possible, Thank you!

Assuming that she has no knowledge of the correct answers to any of the questions, she has decided on a strategy in which she will place four balls (marked A, B, C, and D) into a box. She randomly selects one ball for each question and replaoee the ball in the box. The marking on the ball will determine her answer to the question. There are ve multiple-choice questions on the exam. Complete parts (a) through (d) below. a. What is the probability that she will get ve questions correct?
