The whole paragraph is like this:
An experiment has three possible outcomes, l, J, and K. The probabilities of the outcomes are 0.25, 0.35, and 0.40, respectively. If the experiment is to be performed twice and the successive outcomes are independent, what is the probability that K will not be an outcome either time?
I'm not sure about the
K will not be an outcome either time.
Which of the following is the right meaning?
(1) In any of these two times, K will not be an outcome.
(2) K will not be an outcome in both time, which means, K can be the outcome in one time at most.
The right answer is 0.64, which supports (1), but I suspect it's wrong..
Does anyone have ideas about this?
