Question 459797: plzzz helppp !!!!
A surgeon makes a medical operation successfully with a probability p=0,8. he will make n=10 medçal operations for a week. what is the probabity of the following evetns:
1) A={ the number of succesful operations is 6}
2)B={at least one of the 10 operations is succesfull}
3)C={the number of succesfu operations is less then 10}
4) find the most probable number of N of the succesfull operations, made by this surgeon.

You can put this solution on YOUR website!

Probability of successful operation = 0.8 = 8/10 ,
probability of unsuccessful operation = 2/10
use binomial method..

1) P(A)= 10C6 *(8/10)^6 * (2/10)^4
2) P(B) = 1 - [ 10C10* (2/10)^10]

3) P(C)= 1 - [ 10C10* (8/10)^10]
