Three reds

What is the probability that when choosing 3 carats from seven carats, all 3 reds will be red?

Correct answer:

p =  1.129 %

Step-by-step explanation:

C3(8)=(38)=3!(83)!8!=321876=56  C3(32)=(332)=3!(323)!32!=321323130=4960  p=100 (38)/(332)=100 56/4960=31351.129%   Verifying Solution:  p1=100 32 31 308 7 6=31351.129 %
