1. Hi guys,

Im really struggling with binomial distribution when it comes to the language.

So for example,
This question:

If the distribution is X~B(20,0.9)

1) Find the probability (P) of more than 15-So would you do the P(X>15)=1-P(X<15)

2)Find the P of less than 18-Would you do the probability of less than 17

3) P of between 12 and 18, inclusive-This is part I struggle with the most!

So if the probability is between two values...Would you do the P of 18 minus P of 11?

Guys a big thank you...
