To determine the probability of obtaining 45 or fewer heads in 100 tosses of a fair coin, you can use the binomial distribution model. The number of trials (n) is 100, and the probability of success (getting heads) on each trial (p) is 0.5. The cumulative probability can be calculated using statistical software or a binomial probability table, yielding a result near 0.5, as 45 heads is close to the mean of 50 heads expected in 100 tosses. For precise calculations, employing the normal approximation to the binomial distribution can also provide an estimate.

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 2 heads in 3 coin tosses?
It is 3/8.
What is the probability of 4 or more heads in 7 tosses of a fair coin?
It is 0.5
What is the probability of getting heads twice out of three tosses?
2 out of 3 i think
