each spin is independant, so it kinda depends on how you interpret the final question

if you flip a coin 8 times, what is the probability that you get heads on the last flip?

amistre64 · Answer

as is, i believe its the same probability as getting a free spin on the first try .....

since we have 1 favorable outcome out of 10 possible outcomes; and a prob is measured between 0 and 1

the prob of a free spin, all other things being equal, would be 1/10

Consider the work of @jack at http://tinyurl.com/n6xx9jn ---------- 5 Odd segments 1, 3, 5, 7, 9 5 Non-odd segments 2, 4, 6, 8, Free Spins from the past have no influence on future spins, so the chance is 5/10 = 50%
