Given that Margie is practicing for an upcoming tennis tournament. Her first serve is good 20 out of 30 times on average.
Since each trial is independent and there are two outcomes, X no of good serves is binomial with n=6 and p =2/3
Required probability
= Prob that atleast four of 6 times good serve
=
=
Formula used:
P(X=r) =
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

From least to greatest
0.10, 0.1, 0.29, 5.07, 5.6
