nursing student is required to take an online quiz as part of her ongoing training. There are 10 True or False questions on the quiz and she knows the answers to 6. If she needs a score of 8 or better out of 10 to pass the quiz, what is the probability that she will NOT pass the quiz by guessing randomly on the 4 questions she is unsure of?

In the US Congress, the Senate consists of 13 women and 87 men. The President randomly selects members of the Senate to sit in on his meetings. What is the probability of selecting 3 consecutive women? After selecting each person, you do not place them back in the selection pool.

A sample of 2500 patients were taken to assess a medical test.  40% of the sample had a positive test, 563 patients have the disease and tested negative, and 235 patients do not have the disease and tested positive. What is the probability someone has a positive test if it is known they do have the disease?  (round your answer to 4 decimal places) What is the probability someone does not have the disease if their test is known to be negative?  (round your answer to 4 decimal places)

You took  a test with 40 multiple choice questions.  Each question had 5 choices.  What is the probability that you get at least 28 questions correct if you guessed in all of them.

Find the indicated probability. A multiple choice test has 12 questions each of which has 5 possible answers, only one of which is correct. If Judy, who forgot to study for the test, guesses on all questions, what is the probability that she will answer exactly 3 questions correctly?

You took a multiple-choice math test where there were 10 questions and each question had 4 answers to chose from (but only one of them was correct).  What is the probability that you get exactly 9 correct? Be sure to identify your variables.
