Question

Two events, X and Y, are independent of each other. P(Y)= and P(X and Y)=. What is P(X) written as a decimal? Round to the nearest tenth, if necessary.

Answer 1

Answer:

0.4

Step-by-step explanation:

For independent events,

P(X ∩ Y) = P(X)* P(Y)

=>

1/3 = P(X)*(5/6)

solve for P(X) =>

P(X) = (1/3)*(6/5) = 2/5 = 0.4
