Question: "A coin is tossed 8 times. Find the probability P(of exactly 6 occurrences of tails)"

Answer:
When we toss a coin we have 50% of probability to get a tail and 50% probability to get heads.

If we toss the coin 8 times, in order to find P(T=6), we need to use the binomial distribution:

`P = (n!)/(k!(n-k)!) p^(k) (1-p)^(n-k)`
where:
n = total number of events
k = number of successes we want
p = probability of success

Therefore:

`P(T=6) = (8!)/(6!(2)!) 0.5^(6) (1-0.5)^(2)`
= 28 · 0.015625 · 0.25
= 0.109375

Hence, the probability of getting 6 tails out of 8 tosses is D) 10.94%.
