    Using a Binomial Table: Independent Tosses

    This content was COPIED from BrainMass.com - View the original, and get the already-completed solution here!

    A fair coin is given n independent tosses and X denotes the number of heads. Use this model to make the
    following calculations. Use Binomial Table or a TI or Excel
    (a) If n = 10, P(4<=X<=6) =__________ .
    (b)If n = 10, P(4<X<7)=________ .
    (c)If n = 25, P(10<X<=15)=_________ .
    (d) If n = 25, P(X<12)=______ .
    (e) If n = 25, P(X=12)=______ .

    Thanks for letting me work on your post. Here is my explanation:

    (a)P(4<=x<=6)=10C4*0.5^4*0.5^6+10C5*0.5^5*0.5^5+10C6*0.5^6*0.5^4=0.65625

    (b) ...
