[計量] CAT test7
1.an experiment has 3 outcomes,I,J,K
the probabilities of the outcomes are 0.25 0.35
and 0.40,respectively. if it would be performed twice
and the successive outcomes are independent, what is the probability
that K will not be an outcome either time?
~~~~~
-----------------
答案是0.36
我的疑問是...難道是直接0.6^2嗎?
不用算另外兩次的機率嗎? 也就是(0.25*0.35*0.6)^2?

謝謝^^
