No. It is 1/2.
The probability of each coin flip, independently, is 0.5 or 50%. The probability of getting one result (either heads or tails) four times in a row is 0.5 to the fourth power or 0.0625, which equals 6.25%
The probability of Tails on the first toss is 1/2.The probability of Tails on the second toss is 1/2.The probability of Tails on the third toss is 1/2.The probability of Tails on the fourth toss is 1/2.The probability of Tails on the fifth toss is 1/2.The probability of Tails on the sixth toss is 1/2.The probability of Tails on the seventh toss is 1/2.The probability of all of them is (0.5 x 0.5 x 0.5 x 0.5 x 0.5 x 0.5 x 0.5) = (0.5)7 = 0.0078125= 0.78125 %
I'm assuming that a "1-8 spinner" is similar to an eight-sided die, so the probability of spinning a 10 is zero. When throwing dice, or flipping a coin, etc., each outcome is independent. That is, it's not influenced by the previous outcome(s). So if you get three 8s in a row then the probability of getting an 8 on the fourth throw remains at 1/8. The probability of an 8 on each and every throw is always 1/8.
1/6 for all 6 numbers.-- On the first roll, the probability of a ' 1 ' is 1/6 .-- On the second roll, the probability of a ' 2 ' is 1/6 .-- On the third roll, the probability of a ' 3 ' is 1/6 .-- On the fourth roll, the probability of a ' 4 ' is 1/6 .-- On the fifth roll, the probability of a ' 5 ' is 1/6 .-- On the sixth roll, the probability of a ' 6 ' is 1/6 .So the probability of rolling 1 - 2 - 3 - 4 - 5 - 6 in six rolls is (1/6)6 = 0.000021433 = 0.0021%
For exactly two; we take the chance that for the first two coins come out heads and the second 2 come out tails. and then we multiply by the number of different possibilities. (i.e it could be the first and third or the first and fourth). so we get .5*.5*.5*.5*6=.375=37.5%if you want 2 or greater. the answer by similar logic is .5625 or 56.25%
The probability of the first one is 1/6 .The probability of the second one is 1/6 .The probability of the third one is 1/6 .The probability of the fourth one is 1/6 .The probability of all four is (1/6)4 = 0.0007716 (rounded) = 0.077 %
one fourth
If you are talking about the toss of a coin, the probability for a head coming up on the fourth toss is identical to the probability of a head coming up on the first toss, or the 17th or the 9,437th: Exactly 50/50.
The probability of Tails on the first toss is 0.5 .The probability of Tails on the second toss is 0.5 .The probability of Tails on the third toss is 0.5 .The probability of Tails on the fourth toss is 0.5 .The probability of all four is (0.5 x 0.5 x 0.5 x 0.5) = 0.0625 = 6.25%
1/2. What the previous tosses are has no impact on what a fourth toss of a coin is, so the chance of getting a tails is the same on any throw.
The probability of each coin flip, independently, is 0.5 or 50%. The probability of getting one result (either heads or tails) four times in a row is 0.5 to the fourth power or 0.0625, which equals 6.25%
The probability of getting one heart in a random draw from a 52 card deck is 13 in 52, or 1 in 4. The probability of getting the second heart is 12 in 51 - the third, 11 in 50 - the fourth, 10 in 49. The total probability of getting four hearts is simply the product of those probabilities, or 1320 in 499800. Simplified to least common multiple, that reduces to 11 in 4165.
(4/52)*(3/51)*(2/50) = 24/132600 = 0.000181
One fourth [of an inch] = exactly a quarter of an inch!
3/8 is exactly halfway between one half and one fourth
one fourth
Each die toss is independent; so the probability of 4 on the fourth trial is still 1/6.
