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
