... counting heads and sorting by count, you get ...

... so, the probability of each possible number of heads is 0: 1 in 8, 1: 3 in 8, 2: 3 in 8, and 3: 1 in 8.
The probability of getting tails on a coin is SMALLER than rolling a number greater than 2
you ether use a graph tree diagram or web diagram to answer the possible outcomes of the question possible outcomes meaning the number of outcomes the person will have in the probability or divide the number of favourable outcomes by the number of possible outcomes favorible outcomes meaning the number of outcomes all together
a sample .... i think
The probability of flipping 91 coins and getting a head 91 times in a row is 1/291 or (1/2)91 or 4.039E-28. The (1/2)91 is when there is exactly 91 coin tosses or n = 91. As the number of trials increases so does the probability of at least 1 run of length 91. The average number of coin flips to see 91 in a row is 4.951760157141521e+27
1/3
1 in 2.
1/24
These would be independent events; therefore, we can multiply the probabilities of each of the two events. Probability of flipping a head: 1/2 Probability of rolling an odd number with a single die: 1/6 Required probability : 1/2 x 1/6 = 1/12
The best way to think about this is the following way: What is the probability of flipping heads once? 1/2 What is the probability of flipping heads twice? 1/4 (1/2 * 1/2) Using this we can derive the equation to find the probability of flipping heads any number of times. 1/2n Using this we plug in 25 for n and get 1/225 or as a decimal 2.98023224 x 10-8 or as odds 1:33,554,432
The probability of flipping tails on a perfect coin in a perfect toss is 0.5. The probability of rolling 1 on a die is 1 in 6. Likewise, the probability of rolling 6 on a die is 1 in 6. So the probability of rolling either 1 or 6 is 2 in 6 (which is 1 in 3).
It is 0.25

The probability of rolling any number on a cube can be represented by the formula: X / the number of variables. Since any cube has 6 sides, the probability of rolling any of the numbers 1 through 6 on the cube, can be represented by the formula: X = 1 / 6 = 16.66% The odds or probability of flipping a coin and landing it on either side can be represented by X = the requested result / the number of variables = 1 /2 = 50% Therefore, given the two questions of probability, there is a much greater chance of landing a coin on "tails" rather than rolling a "4".
The probability of flipping a Head is the same as that for a Tail and is 1/2 or 50%. The probability of rolling a particular number on a die is 1/6 since there are 6 numbers. Combining these two probabilities (by multiplication) we have, as the combined probability 1/2 x 1/6 = 1/12 = 0.0833333333333333(the 3 recurs) which as a percentage is 8.33333333333%
