Two events, x and y, are independent of each other. p(y) = 5/6 and p(x and y) =1/3 . what is p(x) written as a decimal?

P(Y) = 5/6
Since they are independent, P(X & Y) = P(Y) * P(X)
Therefore:
1/3 = 5/6 * P(X)     Change 1/3 to 2/6, then multiply both sides by 6/5
2/6 * 6/5 = P(X)    
2/5 = P(X)
Written as a decimal, P(X) = .40 

Letter c so sorry if i’m wrong ):

This makes absolutely no sense at all young man/women
