The urn is eight white and six black balls. We pull four random balls. What is the probability that among them will be two white?

Correct answer:

p =  0.4196

Step-by-step explanation:

C4(14)=(414)=4!(144)!14!=432114131211=1001 C2(8)=(28)=2!(82)!8!=2187=28  C2(6)=(26)=2!(62)!6!=2165=15  p=(48+6)(28) (26)=(48+6)28 15=14360=0.4196
