Web19 sep. 2024 · Sorted by: 7. The answer to your confusion is that in order for three events A, B and C to be mutually independent it is necessary but not sufficient that P ( A ∩ B ∩ C) = P ( A) × P ( B) × P ( C) (condition 1). The other condition that must be met is that each pair of events must also be independent [so A and B must be independent, B and ...

WebThe joint probability mass function of two discrete random variables X and Y is defined as P X Y ( x, y) = P ( X = x, Y = y). Note that as usual, the comma means "and," so we can write P X Y ( x, y) = P ( X = x, Y = y) = P ( ( X = x) and ( Y = y)). We can define the joint range for X and Y as R X Y = { ( x, y) P X Y ( x, y) &gt; 0 }. WebIf events X and Y are mutually exclusive, P(X) = 1/3 and P(Y) = 2/5, P(X∪Y) is. Register. Login. Username.

WebThe probability of either X or Y fails in the examination is P (X ∪ Y) = P (X) + P (Y) − P (X ∩ Y) Given that P (X) = 0.3, P (Y) = 0.2 ∴ P (X ∪ Y) = P (X) + P (Y) − P (X ∩ Y) Since, the failure of X does not depends on the failure of Y, so X and Y are independent events. ∴ P (X ∪ Y) = P (X) + P (Y) − P (X) ∩ P (Y) = 0.3 + 0.2 − 0.3 × 0.2 = 0.5 − 0.06 = 0.44 WebNow P(X = x i;Y = z k x i;Y = y j) will be 0, unless z k x i = y j. orF each pair (i;j), this will be non-zero for only one aluev k, since the z k are all di erent.
