Answer:

4/20 or 1/5

Step-by-step explanation:

number of guesses/total possible outcomes (formula for this question since it is an independent event)

total possible outcomes: 4(# of questions) x 5(# of possible answers in 1 question)

total possible outcomes: 20

number of guesses: 4 x 1(there are 4 questions and you guess 1 answer for each question)

number of guesses: 4

number of guesses/total possible outcomes = 4/20 or 1/5
