Simulate four coins being flipped by generating four random numbers and rounding them to $0($tails$)$ or $1($heads$)$:$>>$nums round$($rand$(1,4))$;

a$)$ Wite a for loop to evaluate the number of coin ips $($evaluated in a nested while loop$)$ required to achieve an outcome ofthree heads and one tail in $18\mathrm{.}000$runs.

b$)$Calculate the mean and standard deviation of the number of flips.Store the results according to the list below:

the number of coin flips on each run in a row vector as variable CountVectorthe mean number of coin flips as variable MeanCount

the standard deviation of coin flips variable stdcount
