Question

An honest coin is flipped 4 times. Given that the coin landed heads up more than two, what is the probability that it landed heads up all four times?

Answer 1

50%

Explanation:

You flip a coin 4 times, with 2 possibilities every flip, heads or tails. So, every time you throw there's a 50% chance you'll throw tails.

Answer 2

probability of getting four head consecutively is 0.2

Explanation:

in an experiment coin is flipped 4 times.

given, coin landed heads up more than two times

outcomes of coin landed heads up more than two times =

SAMPLE SPACE : [ {HHHT}{HHTH}{HTHH}{THHH}{HHHH} ]

chance of getting 4 heads = 1 (HHHH)

Probability =
`(1)/(5)`

hence the probability of getting four head consecutively is 0.2
