Let C(n,m)=n!/(m!(n-m)!)
<br>2. a C(15,10)*(0.65^10)*(0.35^5)
<br> b C(15,15)*(0.65^15)
<br> c C(15,10)*(0.65^10)*(0.35^5)+C(15,11)*(0.65^11)*(0.35^4)
<br> +...+C(15,15)*(0.65^15)
<br>3. We must assume that the number X of points satisfies the normal distribution.
<br>a. P(X>40)=0 since it is out of 3 standard deviation.
<br>b. P(X=0)=0 since it is also ...
