We throw five times the dice. What is the probability that six fits exactly twice?

Correct result:

p =  0.1608


q=160.1667 C2(5)=(52)=5!2!(52)!=5421=10  p=q2 (1q)52 (52)=0.16672 (10.1667)52 10=6253888=0.1608

We would be pleased if you find an error in the word problem, spelling mistakes, or inaccuracies and send it to us. Thank you!
