How to use the binomial law on this ?
P(Y<12 l p=1/2) ??? The answer is suppose to be
1-0.868 =0.132
Can someone explain plsssss
Hey steelmaste.
For a distribution, you need to give a number of trials [i.e. an N parameter].
After that you can use the fact that P(X < a) = 1 - P(X >= a) since P(X < a) + P(X >= a) = 1 since all combinations are taken into account.
