What is the probability of getting heads on three successive tosses of a coin?

How many times would a coin have to show heads in 50 tosses to show an experimental probability of 20 percent more than the theoretical probability of getting heads?
Theoretical probability = 0.5 Experimental probability = 20% more = 0.6 In 50 tosses, that would imply 30 heads.
If a fair coin is tossed ten times what is the probability of getting five heads?
The probability of getting five heads out of 10 tosses is the same as the probablity of getting five tales out of ten tosses. One. It will happen. When this happens, you will get zero information. In other words, this is the expected result.
What is the probability of of tossing heads on the first 6 tosses of a fair coin?
The probability of tossing heads on all of the first six tosses of a fair coin is 0.56, or 0.015625. The probability of tossing heads on at least one of the first six tosses of a fair coin is 1 - 0.56, or 0.984375.
What is the probability of getting exactly two heads in three coin tosses?
33%
What is the probability of getting exactly two heads with 4 coin tosses?
To find the probability of getting exactly two heads in four coin tosses, we can use the binomial probability formula. The number of ways to choose 2 heads from 4 tosses is given by the binomial coefficient ( \binom{4}{2} = 6 ). The probability of getting heads on each toss is ( \frac{1}{2} ), so the probability of getting exactly 2 heads is ( \binom{4}{2} \times \left(\frac{1}{2}\right)^2 \times \left(\frac{1}{2}\right)^2 = 6 \times \frac{1}{16} = \frac{6}{16} = \frac{3}{8} ). Thus, the probability of getting exactly two heads is ( \frac{3}{8} ).
What is the probability of getting 2 heads on all 3 tosses?
The probability is 0, since there will be some 3-tosses in which you get 0, 1 or 3 heads. So not all 3-tosses will give 2 heads.
What is the probability of getting 3 heads from 4 coin tosses?
The probability is 1 out of 5
What is the probability of getting only heads on the two tosses?

2 out of 3 i think
What is the probability of getting heads on all 2 tosses if a fair coin is tossed 5 times?
With 5 coin tosses there are 32 possible outcomes. 10 of these have exactly 2 heads, and 26 of these have 2 or more heads.For exactly two coins are heads: 10/32 = 31.25%For two or more heads: 26/32 = 81.25%
