# Statistics 1 Edexcel watch

1. Two events R and S are independent. P(R/S) = 3/4| and P(S) = P(S' n R'). By letting x equal P(S) and forming an equation for x, or otherwise, find
(a) P(S)
(b) P(S' n R)
(c) Write down P(S/R)

Can someone pls provide me the answer for all of the following?

For P(S) the answer I am getting is 1/4, is it right?
2. Okay, So they are independent which means you can use one of three equations to start with.

I get P(S) = 1/5

Post working, if you'd like someone to check it.
