What is the probability of getting three or fewer heads on eight tosses of a coin?
It is 93/256 = 0.363 approx.
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 probabiltiy that a coin will land on heads in six tosses?
The probability that a coin will land on heads - at least once - in six tosses is 0.9844
What is the probability of getting 3 heads from 4 coin tosses?
The probability is 1 out of 5
What is the probability that a coin that is tossed 10 times what is the probability of it landing on heads 10 times?
The probability is 0.09766%.Each toss has a ½ chance to be heads. To combine probabilities use multiply them. So the probability to get two heads out of two tosses is ½ * ½, and three heads out of three tosses is ½ * ½ * ½. So the exact answer is 0.5^10

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.

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.
What is the probability of getting only heads on the two tosses?
1/4
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 exactly two heads in three coin tosses?
33%
What is the probability of getting 2 heads in 3 coin tosses?
It is 3/8.
What is the probability of getting heads on three successive tosses of a coin?
0.53 = 0.125.
