Find the probability that a randomly generated bit string of length 10 does not contain a 0 if bits are independent and if a 0 bit and a 1 bit are equally likely.

Answer:

Step-by-step explanation:

From the given information; Let's assume that  R should represent the set of all possible outcomes generated from  a bit string of length 10 .

So; as each place is fitted with either 0 or 1

[tex]\mathbf{|R|= 2^{10}}[/tex]

Similarly; the event E signifies the randomly generated bit string of length 10 does not contain a 0

Now;

if  a 0 bit and a 1 bit are equally likely

The probability that a randomly generated bit string of length 10 does not contain a 0 if bits are independent and if a 0 bit and a 1 bit are equally likely is;

[tex]\mathbf{P(E) = \dfrac{|E|}{|R|}}[/tex]

so ; if bits string should not contain a 0 and all other places should be occupied by 1; Then:

[tex]\mathbf{{|E|}=1 }[/tex]   ; [tex]\mathbf{|R|= 2^{10}}[/tex]

[tex]\mathbf{P(E) = \dfrac{1}{2^{10}}}[/tex]
