75% is not correct.

The odds of flipping 4 independent coins is the same as flipping one coin 4 times.

The number of outcomes of 4 flips is 2^4 or 16.

The number of ways to exactly get 3 Heads is 4 (THHH, HTHH, HHTH, HHHT) so your chance of flipping 3 heas is 4/16 or 25%.

If you include the occurance that produced 4 of 4 Heads, then you get 5/16 or 31.25%.

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 flipping three coins and all of them land up on heads?

The probability of the first coin landing heads is half (or 1/2). Similarly, the probability of the second and third coins landing heads are also 1/2 in each case. Therefore, the probability of having three heads is: (1/2)(1/2)(1/2) = (1/8)


What is the probability of getting all heads on a toss of three fair coins?

1/2 * 1/2 * 1/2 = 1/8 = 12.5%

What is the probabality of flipping three heads when flipping three coins one after another?

The probability of flipping a coin three times and getting two heads is?

There are 8 permutations of flipping a coin 3 times, or of flipping 3 coins one time. They are, with the permutations of two heads bolded...TTTTTHTHTTHHHTTHTHHHTHHH... thus, the probability of flipping a coin 3 times and getting 2 heads is 3 in 8, or 0.375.


What is the probability of not tossing three heads with three fair coins?

The probability of something NOT happening is the complement of the probability of something happening. Since the probability that you DO have 3 heads is 1/8 (that is, 1/2 cubed), the complement is 1 - 1/8 = 7/8.


What is the probability of getting three or more heads when four coins are flipped?

Number of possible outcomes with 4 coins = 2 x 2 x 2 x 2 = 16.Number of successes = 2. (Three heads or four heads)Probaility of success = 2/16 = 1/8 = 12.5 percent
