I was going to suggest: conditioned on what? Conditional probability, written P(A|B), is the probability that A happens given that B already is/has/will happen. For instance the probability of snow is the probability that it is freezing and that you have precipitation, but the probability that it snows given that it is already precipitating is just the chance that it is cold enough. Probability of A given B, so what's the condition B in your question: P(4 heads| what?)..........

6.5% or 1/16. If you flip the coin 8 times, then you are suppose to get 4 heads in a row.

To find the probability of two independant events, you multiply the probablilty of each individual event. Since there is a relatively 1/2 of landing heads, it's
1/2 * 1/2 * 1/2* 1/2*
= 1/16
or 6.25%

This is not a conditional probability. It is just a probability.
p(4H) = (1/2)^(4) = 1/16

slightly less then 1/16. the heads side weighs slightly more then the tails side, therefore causing it to land downwards with the tails up. if you flipped the coin 100000 times, it would not come out to be 50/50, but more like 53/47...

1/2 each flip so (1/2)^4=1/16 or .0625

1/2 x 1/2 x 1/2 x 1/2
So 1/16

Meh. Our coins are fair in Canada.
