a test has multiple choice questions with 5 choices for each answer; only one answer is correct for each question.
suppose a student guesses the answer to each question. assuming the guesses are independent, find the probability
that the student will guess correctly when answering two questions.
o 1/5
1/10
01/25

1/25

Step-by-step explanation:

The probability of guessing the first question correct is 1/5

The probability of guessing the second question correct is 1/5

Since they are independent

P(correct, correct) = P(1st correct) * P(2nd correct)

                               = 1/5 * 1/5

                               = 1/25

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1

1010: 3030

is it i think
