If it is a T/F test; probability correct for each question is 0.5. Since there are 4 questions, raise 0.5 to the 4th power; e.g. (0.5)4. So, probability all correct is 0.0625. If a 4 part multiple choice, P(correct) = .25 so raise .25 to the 4th power, or .003906.
The answer depends on how well you do in the quiz: that is not a random experiment.
The conditional probability is 1/4.
To calculate the probability of getting at least four heads when flipping a coin six times, we can use the binomial probability formula. The total number of outcomes for six flips is (2^6 = 64). The probabilities for getting exactly four, five, and six heads can be calculated using the binomial formula, and their sum gives the total probability of getting at least four heads. This results in a probability of approximately 0.65625, or 65.625%.
Assuming it is a fair coin, the probability is 1/24 = 1/16.
The probability is 1/4

Probability of each question correct is 1/4 or 0.25. Since there are 5 questions, raise 0.25 to the 5th power or (0.25)5. So, probability all correct is 0.0009765.
0.54 or 0.0625 or 1/16.
The probability of NOT getting heads is (1/2)4=1/16 Therefore the probability of getting heads is 1-1/16=15/16
Oh, what a happy little question! Let's break it down. The probability of getting heads on a single flip is 1/2, and the probability of getting tails is also 1/2. So, the probability of getting HTTH in that specific order on four flips would be (1/2) * (1/2) * (1/2) * (1/2) = 1/16. Just remember, there are no mistakes, just happy little accidents in probability!

No. Probability is defined as a number between 0 and 1 (100 percent). If you have four oil wells, each with a probability of hitting being 30%, then the probability of at least one hitting is 100% - (100% - 30%)4, or about 76%.
