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.

The probability of getting heads on a single coin flip is 0.5. To find the probability of getting heads four times in a row, you multiply the probability of getting heads for each flip: (0.5 \times 0.5 \times 0.5 \times 0.5 = 0.5^4 = 0.0625). Thus, the probability of flipping heads four times in a row is 6.25%.
Each toss has a 1/2 probability of getting heads. Each toss is an independent event. So three heads in a row (heads AND heads AND heads) would have a probability of:1/2 * 1/2 * 1/2 = (1/2)^3 = 1/(2^3) = 1/8 = 12.5%
The odds of getting heads on a single coin flip are 1 in 2. To find the probability of getting three heads in a row, you multiply the probability of getting heads on each flip: ( \frac{1}{2} \times \frac{1}{2} \times \frac{1}{2} = \frac{1}{8} ). Thus, the odds of getting three heads in a row when flipping a coin are 1 in 8.
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.
the probability of getting heads-heads-heads if you toss a coin three times is 1 out of 9.
For 3 coin flips: 87% chance of getting heads at least once 25% chance of getting heads twice 13% chance of getting heads all three times
It is 1/8 = 0.125

Since a coin has two sides and it was tossed 5 times, there are 32 possible combinations of results. The probability of getting heads three times in 5 tries is 10/32. This is 5/16.
The probability of getting heads on a single coin flip is 0.5. To find the probability of getting heads four times in a row, you multiply the probability of getting heads for each flip: (0.5 \times 0.5 \times 0.5 \times 0.5 = 0.5^4 = 0.0625). Thus, the probability of flipping heads four times in a row is 6.25%.
It is (1/2)3 = 1/8 or 0.125

The probability of getting all heads if you flip a coin three times is: P(HHH) = 1/2 ∙ 1/2 ∙ 1/2 = 1/8. The probability of getting all tails if you flip a coin three times is: P(TTT) = 1/2 ∙ 1/2 ∙ 1/2 = 1/8. The probability of getting all heads or all tails if you flip a coin three times is: P(HHH or TTT) = P(HHH) + P(TTT) = 2/8 = 1/4.
The probability of flipping a coin 3 times and getting 3 heads is 1/2
Each toss has a 1/2 probability of getting heads. Each toss is an independent event. So three heads in a row (heads AND heads AND heads) would have a probability of:1/2 * 1/2 * 1/2 = (1/2)^3 = 1/(2^3) = 1/8 = 12.5%
