What is the probability of getting exactly 7 out of 12 multiple choice questions right if a student randomly guesses one of the five possible choices for each question?
It is 0.0033
What are the odds of getting 100 percent on a 10 question multiple choice test where each question has 2 possible answers?
The odds of getting 100 percent on a 10 question multiple choice test with 2 possible answers for each question can be calculated using the probability formula. Since there are 2 options for each question, the probability of getting a question right by guessing is 1/2 or 0.5. To calculate the probability of getting all 10 questions correct by guessing, you would multiply the probability of getting each question right (0.5) by itself 10 times, resulting in a probability of (0.5)^10, which is approximately 0.0009765625 or 0.09765625%.
If a box contains one red ball and one blue ball and two people touch one ball randomly with a one in two chance of picking either what is the chance of the blue ball being picked twice?
One in four. The possibilities are; Red Red Blue Red Red Blue Blue Blue That means the number of ways an event can occur is one, while the number of possible outcomes is four. The definition of probability is the number of ways the event can occur over the number of possible outcomes, hence 1/4

In a twenty question true false examination a student must achieve eight correct answers to pass if student answers randomly what is the probability that student will fail?
The probability this student will fail is the same as the probability that some other student will flip a fair coin 20 times and get less than 8 heads, i.e., more than 12 tails. There are 2^20 possible different-looking sequences of 20 coinflips, which we assume all have equal probability. Of those sequences, 1 has no heads at all, 20 have exactly 1 head, 190 have exactly 2 heads, ... and 77520 have exactly 7 heads. So we sum up all those possible ways to fail and we get ... ... ... I'm assuming that the student answers randomly, flipping a fair (50:50) coin on each question to choose "true" or "false". In that special case, it doesn't matter how many of those twenty questions are true or how many are false. (If the student answers randomly by flipping an unfair coin, say a 25:75 coin, then it does matter how many of those questions are true -- I'll let you figure that one out).
You sit down to take a true-or-false test with 6 questions If you randomly guess on all questions how many possible outcomes are there for the 6-question test?
The number of possible outcomes would be 2^6 = 64, since each of the six questions have two possible outcomes.
When did Lenny Aisha die where?
Sorry, but that question is unanswerable. The brain tree randomly generates outcomes. There fore there is no set answer.

What is the probability of randomly choosing a vowel from the letters a b c d e?
There are 5 letters in the set {a, b, c, d, e}, and 2 of these letters are vowels (a, e). Therefore, the probability of randomly choosing a vowel from this set is the number of favorable outcomes (2 vowels) divided by the total number of possible outcomes (5 letters), which equals 2/5 or 0.4.
