Question

Three coins are tossed in succession. What is the probability of heads-tails-heads?

1/2
1/6
1/8

Answer 1

1/6 there are 2 sides to each coin :)

Answer 2

okay fine, 3 coins two sides each. = 6 sides. you have 1 chance of getting one of those sides. =1/6

Answer 3

The probability of a head is 1/2, and the probability of a tail is 1/2.
You multiply the probabilities of each event to get the new probability :)

Answer 4

\( \color{Black}{\Rightarrow\Large {1 \over 2} \cdot {1 \over 2} \cdot {1 \over 2} = {1 \over 2^3} }\)

Answer 5

oh. .-. oops

Answer 6

Nah it's all fine

Answer 7

so its 1/8

Answer 8

yeah. Parthicus was right
