Hi!
I'm taking a course that requires some programming background, but I'm a
complete novice in the field.
when asked to generate a list of 20 uniform random numbers, is it alright if
I put in >randu, and just copy-paste the first 20 numbers?? Or is there, as
I suspect, a better way of calling ou

ok, so suppose a coin is tossed 1000 times. Each time head occurs, we win a
dollar, otherwise we lose a dollar. Let S(n) be our accumulated winnings
after n tosses. For instance, if the sequence HHHTT occurs in the first five
tosses, then S(5) = $1.00 wheras if the sequence H occurs, S(5) =
Ok, so n= the toss number, and s(n) is the accumulated winnings after n
tosses. Now, each time we have a heads, we win a dollar, and each time we
have a tails, we lose a dollar. So, s(n) is th sign changes in 1000 tosses.
In the beginning, S(0) must be 0, and S(-1) must be zero too. ok, so if on
Thank you guyz. your codes gave me the results I was looking for. And thanks
for the reference suggestion. Lastly, how do I code the frequency of heads?

THANKYOU guyz! yes, Jim's code was right (it was similar to someone
elses)I somehow missed his reply!
Yes, that was exactly what i was looking for. lastly, how do i find the
frequency of heads perhaps?
