Question 371919: What is the probability that the number of heads will be less than or equal to 1200 out of 2500 tosses?
P{H<= 1200 when you toss a coin 2500 times}
define X_k ={5 if H; 10 if H <---- should be on next line in braket
I asked this question before but only got the end reslut, which I already have. I was wondering ig someone could please help me work this out step by step so that I can better understand it.

Binomial Problem with n = 2500 ; p = 1/2

Using a TI-84 I get:
P(x <= 1200) = binomcdf(2500,0.5,1200) = 0.0238

define X_k ={5 if H; 10 if H <---- should be on next line in braket
Comment: That does not make any sense.
Cheers,
