A10 bit string is to be randomly picked from all possible 10 bit strings. what is the probability that you picked a string with at least one zero?

0.9990

Step-by-step explanation:

Given : The number of bits in a string = 10

The value taken by a bit is either 0 or 1.

Therefore, the probability that the bit is zero =

Binomial probability distribution formula :-

, where P(x) is the probability of getting success in x trials , n is the total number of success and p is the probability of getting success in each trial.

Now, the probability that you picked a string with at least one zero is given by :-

Hence, the  probability that you picked a string with at least one zero = 0.9990

-4

step-by-step explanation:

(-4+8)=-(4-8)=-8+4=-4
