Yanıt Açıklaması:
There are different possible outcomes and the sample space is
S = {X1X2, Y1Y2, Y1Y3, Y2Y3, X1Y1, X1Y2, X1Y3, X2Y1, X2Y2, X2Y3}
If the event “one brand X and one brand Y phone is chosen” is denoted by E, the elements of E are .
E = { X1Y1, X1Y2, X1Y3, X2Y1, X2Y2, X2Y3}
The probability that event E will occur.
P(E)=n(E):n(S) = 6:10 =0.6
