1. The problem statement, all variables and given/known data Find the probability that a randomly generated bit string of length 10 begins with a 1 or ends with a 00 if a)a 0 bit and a 1 bit are equally likely. b)The probability that a bit is a 1 is .7 c)The probability that the ith bit is a 1 is 1/2i for i=1,2,3,...,10 2. Relevant equations 3. The attempt at a solution Since I know that the length is 10, and that the first and last two spots are already selected, I only have to worry about the middle 7 spots. A bit can only be 2 choices 0 or 1. a) If the odds are the same for both, then I just calculated (1/2)7 based on the 7 remaining choices. b) Probability here would be (.7)7 going by the same remaining choices. c)For this I did (1/2)(1+7)*7/2 which would equal a probability of (1/2)28. Was my approach to this problem correct?
