When a coin is tossed three times what is the probability of getting at most two heads?
The opposite of getting at most two heads is getting three heads. The probability of getting three heads is (1/2)^2, which is 1/8. The probability of getting at most two heads is then 1 - 1/8 which is 7/8.
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 getting only heads on the two tosses?
1/4
What is the probability of getting heads on the one flip of coin?
There are two sides to the coin, so the probability of getting heads or tails on one flip of the coin is 1/2 or 50%.
What is the probability of getting two heads in unbiased coin?
In two tosses: 1/4.

What is the probability of getting 2 heads when 2 coins are tossed?
The probability of tossing two heads in two coins is 0.25.
What is the probability of flipping a coin twice and getting two heads?
The probability is 25%. The probability of flipping a coin once and getting heads is 50%. In your example, you get heads twice -- over the course of 2 flips. So there are two 50% probabilities that you need to combine to get the probability for getting two heads in two flips. So turn 50% into a decimal --> 0.5 Multiply the two 50% probabilities together --> 0.5 x 0.5 = 0.25. Therefore, 0.25 or 25% is the probability of flipping a coin twice and getting heads both times.
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.
The probability of flipping a coin twice and getting two heads is?
The probability of this is 50%. 2/4
What is the probability of getting only heads on the two tosses?
1/4
What is the probability of getting heads on the one flip of coin?
There are two sides to the coin, so the probability of getting heads or tails on one flip of the coin is 1/2 or 50%.
What is the probability of flipping 4 coins and getting all heads or all tails?
The probability of getting all heads is 1/24 = 1/16 The probability of getting all tails is also 1/24 = 1/16 The probability of all heads or all tails is the sum of the two = 1/8
