Question
On a biased coin the probability of it showing heads for a given coin toss is 0.52. In a sequence of tosses, what is the probability of getting the first tail on flip 5?
I can just do a tree diagram for this and figure it out the slow way, but if I get this in an exam, that'll take a whiile. Is there a faster way of solving this?

4 consecutive heads, then a tail
.52^4 * .48
.52^4 * .48
