A multiple choice test has five questions each with five choices for the answer. what is the probability of getting all 5 right

2 answers:

5 0

5 times 5 means there are 25 total choices

since there is a total of five questions and each question has one correct answer 5out of 25 are correct

so you have a 5/25 chance which simplifies to 1/5th probability

The probability of getting all 5 right would be 1/3125

This is because each question has one choice. Making it a 1/5 chance for each question.

Now if you combine if you add the rest you will have to calculate.

You would do the calculation by multiple the chance for a correct answer for each question together.

1/5 x 1/5 x 1/5 x 1/5 x 1/5 = 1/3125

I hope this helped!
