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.

What is the probability of getting 75 percent on a four question quiz?
The answer depends on how well you do in the quiz: that is not a random experiment.
What is the probability of tossing four coins and getting four heads if the first two tosses are heads?
The conditional probability is 1/4.
What is the probability of tossing four coins and getting tails on all four?
Assuming it is a fair coin, the probability is 1/24 = 1/16.
What is the probability of getting three tails and a head when a coin is tossed four times?
The probability is 1/4
There are five questions on a quiz with four possible answers what is the probability you get 100 percent?
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.

What is the probability of flipping four coins and getting four heads?
0.54 or 0.0625 or 1/16.
What is the probability of flipping four coin's to get a head?
The probability of NOT getting heads is (1/2)4=1/16 Therefore the probability of getting heads is 1-1/16=15/16
If four fair coins are tossed what is the probability of getting two tails?
50%
A fair coin is flipped 4 times what is the probability of getting more than 3 heads?
The probability of flipping a fair coin four times and getting four heads is 1 in 16, or 0.0625. That is simply the probability of one head (0.5) raised to the power of 4.
Can probability be higher than 100 percent... Say you have 4 oil wells each with a 30 percent chance of hitting ...Isn't the calculated probability of one hitting 120 percent?
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%.
