Answer: 5.000
Step-by-step explanation:
The formula to find the standard deviation for binomial distribution is given by :-
[tex]\sigma=\sqrt{np(1-p)}[/tex], where p is the probability of getting success in each trial and n is the number of trials.
Given : The probability of flipping a coin and noting Heads is = 0.50
The total number of trials = 100
Then , the standard deviation of Heads to be noted will be :-
[tex]\sigma=\sqrt{100(0.50)(0.50)}=5.000[/tex]
Hence, the standard deviation of Heads to be noted = 5.000
