A test consists of six

a. True

b. False questions. a student who forgot to study. what is the probability that the student answers exactly tree questions correctly

True/false questions grant a 50% chance for each question. If there are 6 questions, the probability of getting 3 right is 50%. You can find the answer by multiplying the percentages for each outcome.

50% * 50% = 25%

The student ultimately has a 25% chance of getting 3 of the 6 true/false questions correct.
