Question 1197316: b. Hospital records show that 75% of the patients will recover from a certain disease.
i.What is the probability that 2 out of 6 patients selected at random will die from a certain disease?
ii. What is the probability that 4 out of the 5 patients selected at random will recover from a certain disease?
c. Five of 10 new buildings in a city violate the building code. A random sample of three buildings
selected for inspection.
*)What is the probability of none of the buildings violate the building code in a sample of 3 buildings

*)What is the probability of at least one of the new buildings violate the building code in a sample of 3 buildings?

Hi  
Binomial Probability:  n = 6, p(recover) = .75, p(die) = .25
what then is the probability that the inspector's sample contains:
Using TI or similarly an inexpensive calculator like an Casio fx-115 ES plus
P(2 die) =.2966 (calculator)
0r
 

 P(2die) =  =.2966
..............
n = 5, p(recover) = .75, p(die) = .25
P(x = 4 recover ) = .3955(calculator)   Or  = .3955
...............
n = 3, p(violate code) = 5/10 = .5
P(x=0) = .125 (calculator)
P(at least one violate) = 1 - P(x=0) = 1 - .125 = .875
