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 showing at least one head from 4 coin tosses?
To find the probability of getting at least one head in 4 coin tosses, it's easier to calculate the complementary probability of getting no heads at all (i.e., getting all tails). The probability of getting tails in a single toss is 0.5, so for 4 tosses, the probability of all tails is ( (0.5)^4 = 0.0625 ). Therefore, the probability of getting at least one head is ( 1 - 0.0625 = 0.9375 ) or 93.75%.
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%
A coin is tossed 5 times find the probability that the 6th toss is a tail given tht the first 5 tosses were all tails?
The chance is 50%-50% that it will be heads or tails; this does not change regardless of the number of previous tosses and their results.
What is the probability that a coin lands heads up on three consecutive tosses?
For each toss, the probability that it'll land heads up is 1/2 So 1/2 * 1/2 * 1/2 = 1/8, or .125 There is a 12.5% chance that it will land heads-up all 3 times.
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 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 would you describe the pattern in probability of getting all heads as the number of coin tosses increases?
If the coin is fair, the probability of getting all heads will decrease exponentially towards 0.

What is the probability of getting heads on all 3 tosses if a fair coin is tossed 3 times?
1/2 x 1/2 x 1/2 = 1/8 The probability is 1 chance in 8 sequences, or .125
A fair coin is tossed 3 times what is the probability it will land on heads all 3 tosses?
0.5*0.5*0.5 = 0.125 or 1/2*1/2*1/2 = 1/8
What is the probability that at least 1 head appears in 7 tosses of a fair coin?
To find P( at least 1 head in 7 tosses) we can find P( no heads) and subtract that from one. Alternatively, we need to find P ( 1 head) + P ( 2 heads )+...+ P(7 heads) Since P of no heads is P( all tails) this is (1/2)7 =.0078125 ( 1/128 as a fraction) Now 1-(1/128)=127/128 or .9921875
What is the probability of flipping 4 coins and getting all heads or all tails?
The probability of getting all heads is 1/24 = 1/16 The probability of getting all tails is also 1/24 = 1/16 The probability of all heads or all tails is the sum of the two = 1/8
What is the probability of obtaining exactly three heads in four flips of a coin given that at least one is a head?
50-50. each toss is independent of any previous toss. if all tosses are to be heads/tails then each toss you multiply by the number of chances. i,e. 2, starting with 1. three heads in a row is 1x2x2
What is the probability that a coin will land on tails 75 percent of the time if flip four times?
For 4 coin tosses, there are 16 possible outcomes. Tails on 75% of 4 tosses is 3 times tails, and 1 time heads. This occurs in 4 of those 16 possibilities, so the probability is 4/16 = 1/4 (or 25%). But if the question is 'what is the probability that it's tails at least 75% of the time, then you have to add in the 1 where all 4 are tails, then you have 5/16 (or 31.25%).
