Answer: 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
