If `X and Y` are independent binomial vatiates `B(5,1/2) and B(7,1/2)` and the value of `P(X+Y=3)` is

If P(A)=2/5 and P(B)=1/3 , A and B are independent events, then find the value of P(AnnB) .

Suppose X is a binomial variate B(5,p) and P(X=2)=P(X=3), then p is equal to

If A and B are independent events and if P(A) = 1/2, P(B)= 2/5, then P(A cap B) is equal to :

If A and B are independent events and if P(A) = 1/3, P(B)= 2/5, then P(A cap B) is equal to :

If (x/3+1, y-2/3)=(5/3, 1/3) , find the values of x and y.

Multiply the binomials. (x-y) and (3x+ 5y)

If the polynomial 7x^(3)+ax+b is divisible by x^(2)-x+1 , find the value of 2a+b.

If X[(2),(3)] + Y [(1),(1)] = [(10),(5)] , find the values of X and Y.
