A coin is tossed, what is the probability that two consecutive
heads or two consecutive tails occur in at most
four tosses? Draw a tree diagram first.
Homework Answers
In the given tree diagram, i have tick out
the outcomes having two consecutive tails or two consecutive
heads.and the total number of outcomes having two consecutive heads
or tails is 14 so,
Required probability= 14/16= 7/8=0.875
