Flipping coins results in a probability of 0.4 heads for coin 1 and 0.7 heads for coin 2, respectively. One of these coins is picked at random and flipped a total of 10 times.
(a) What is the probability that exactly 7 of the 10 flips land on heads? 
(b) Given that the first of these ten flips lands heads, what is the conditional probability that exactly 7 of the 10 flips lands on heads?
