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.

You can put this solution on YOUR website! What is the probability that the number of heads will be less than or equal to 1200 out of 2500 tosses?
---
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,
Stan H.
