Suppose you have a coin that lands on Heads with probability 0.6
There are three coin flips defined as X. Heads count 1 and tails count 0 – e.g., if three heads then X= 3; if a
head and two tails then X = 1; if three tails the X = 0.
What is the expected value of X?
I'm confused as to how to start this problem?
