# Using a Binomial Table: Independent Tosses

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)=______ .

#### Solution Preview

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) ...
