What is the probability of getting at least one head in 3 coin tosses?
7/8
Summary: A coin is tossed 3 times. The probability of getting at least one head is 7/8.
What is the probability of at least 1 head?
At least one heads has a probability of 100%, minus the probability of all tails. With an unbiased coin, the chance of the first toss being tails is 50%.
What is the probability of getting at least one head when we are tossing the coin 7 times?
Since the probability of flipping tails for one flip is 1/2, the probability of flipping seven tails straight is 1/2 to the 7th power, or 1/128. Therefore, the probability of getting at least one head is 1 – 1/128 = 127/128.
What is the probability of getting at least one head in 5 coin toss?
i.e. The probability of getting 0 heads is (1/2) to the power of 5 = 1/32. Therefore the probability of getting at least one head is 31/32.
What is the probability of flipping 3 heads and 1 tail?
1/4
N=3: To get 3 heads, means that one gets only one tail. This tail can be either the 1st coin, the 2nd coin, the 3rd, or the 4th coin. Thus there are only 4 outcomes which have three heads. The probability is 4/16 = 1/4.
What is the probability of getting 4 consecutive heads?
The probability of getting a heads first is 1/2. The probability of getting 2 heads in a row is 1/2 of that, or 1/4. The probability of getting 3 heads in a row is 1/2 of that, or 1/8. The probability of getting 4 heads in a row is 1/2 of that, or 1/16.
What is the probability of getting 4 heads when 7 coins are tossed?
So there are 35 different outcomes with exactly 4 heads, out of 2^7 = 128 possible outcomes total. So the probability of scoring exactly 4 heads is 35/128.
What is the probability of flipping 7 coins and getting all heads?
I know if you flip a coin 7 times, the odds of getting 7 heads in a row is 1 in 27 or 1 in 128.
What is the probability of getting exactly 3 tails?

What is the probability of flipping exactly 3 heads?
When a certain coin is flipped, the probability of heads is 0.5. If the coin is flipped 6 times, what is the probability that there are exactly 3 heads? The answer is 516.
What is the probability of flipping 2 coins and getting 1 Heads 1 tails?
0.5
As you can see from the picture, the probability of getting one head and one tail on the toss of two coins is 0.5.
What is the probability of getting at least 1 tail when 2 coins are tossed simultaneously?
When two coins are tossed simultaneously, the sample space is given by : S = {HH, HT, TH, TT} where, H is the appearance of Head and T is the appearance of the Tail on the coin. Hence, the probability of getting Head on one coin and Tail on the other coin is equal to 12. This is the final answer.
How many outcomes have at least 3 heads?
Because each flip of the coin offers two possibilities and we are flipping 6 times, the multiplication principle tells us that there will be: 2 · 2 · 2 · 2 · 2 · 2=26 = 64 possible outcomes. How many outcomes will have exactly 3 heads? ) = 20.
