A multiple choice test has 5 questions.

There are 4 choices for each answer.

If you GUESS each answer, what is the probability that you get

AT LEAST one right answer?

The event that “you get AT LEAST one right answer” = the event that

“you do NOT get all wrong answers”.

in how many ways can you

answer this question incorrectly?

A multiple choice test has 5 questions.

There are 4 choices for each answer.

# ways of answering all of the questions = 4 x 4 x 4 x 4 x 4 = 1024

If you GUESS each answer, what is the probability that you get

AT LEAST one right answer?

The event that “you get AT LEAST one right answer” = the event that

“you do NOT get all wrong answers”.

# ways of answering each question incorrectly = 3 x 3 x 3 x 3 x 3 = 243

P ( you get all wrong answers ) = 243
