Suppose we wanted to create a 12-digit bit string (a bit string is a binary number consisting of only ones and zeros).
How many different 12-digit bit strings are possible?
For this one I did [math]2^{12}[/math] [math] = 4096[/math] Different strings
What is the probability that a12-digit bit string has exactly five ones but begins and ends in zero?(Hint: Remember, all of the different 1’s and 0’s are indistinguishable from one another.)
What is the probability that a12-digit bit string has at least eight ones but begins and ends in zero? (Hint: break it up into cases)
The last 2 have me a bit puzzled as I am not sure where to begin. Could someone tutor me.
