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?
(A) 0.36
(B) 0.40
(C) 0.60
(D) 0.64
(E) 0.80

C
need's an explanation
please can yu post answers also..
(1-.4)(1-.4) = .36 A
(1-,4)(1-,4)= .36 so A is correct answer
hERE THE EVENTS ARE INDEPENDENT SO WE NEED TO DO ADDITION .
THE PROBBILITY OF NOT GETTING K IS PROBABILITY OF GETTING I and j which is respectively 0.25 and 0.25. so for both the time the probability fo getting i and j is
2(0.25)+2(0.35)=0.50+0.70+1.20/2=0.60.
