What is the probability of getting 100 percent on a four question quiz?
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 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.

one out of four

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%.
