A weighted coin has a probability of 0.6 of getting a head and 0.4 of getting a tail.

(a) In a series of 30 independent tosses what is the probability of getting the same number of heads as tails? [2]

(b) Find the probability of getting more than 7 heads in 10 tosses? [3]

(c) Find the probability of 4 consecutive tails followed by 2 tails in the next 6 tosses. [2]
