∙ 10y ago
P(0 heads) = 1/16
P(1 head ) = 1/4
P(2 heads) = 6/16 = 3/8
P(3 heads) = 1/4
P(4 heads) = 1/16

A coin is flipped 2 times and the number of heads is observed. Find the probability of tossing 2 heads or 2 tails.?
It is 1/2.
If you flipped two coins what is the probability that the first coin is heads?
The probability is always 50/50 even if you flipped 100 or 1000000 coins.
What is the chance that that 2 flipped coins both come up heads?
The probability that 2 flipped coins both come up heads is 0.52 or 0.25
What is the probability of a coin landing on heads twice when it is flipped 2 times?
25%
2 coins are flipped. What is the probability of landing one heads and one tails?
It is 1/2.
A coin is biased so that the probability a head comes up when it is flipped is 0.6 What is the expected number of heads that comes up when its flipped 10 times?
Multiply the probability by the number of times the experiment was carried out. 0.6x10=6

An experiment is conducted in which two fair coins are tossed and the number of heads is recorded. The binomial random variable, X, is the number of heads?
thas so true
What is the chance that that 2 flipped coins both come up heads?
The probability that 2 flipped coins both come up heads is 0.52 or 0.25
What is the probability of heads commming up when a coin is flipped?
Fifty percent (50%)
What is the probability of flipping 3 heads?
The answer depends on how many coins are flipped, and how often.
What is the probability of a coin landing on heads twice when it is flipped 2 times?
25%
If a coin is flipped twice what is the probability that both will be heads?
The sample space is HH, HT, TH, HH. Since the HH combination can occur once out of four times, the probability that if a coin is flipped twice the probability that both will be heads is 1/4 or 0.25.
What is the probability of flipping heads on the coin?
The probability of flipping Heads on a coin is 1 - a certainty - if the coin is flipped often enough. On a single toss of a fair coin the probability is 1/2.
What is the probability that a coin flipped four consecutive times will always land on heads?
The probability that a coin flipped four consecutive times will always land on heads is 1 in 16. Since the events are sequentially unrelated, take the probability of heads in 1 try, 0.5, and raise that to the power of 4... 1 in 24 = 1 in 16
A coin is flipped eight times What is the probability that the outcome will NOT be eight heads?
Probability of not 8 heads = 1- Prob of 8 heads. Prob of 8 heads = 0.5^8 = 0.003906 Prob of not 8 heads= 1- 0.003906 = 0.99604
