Sets R and S each contain three distinct positive integers. If integer r is randomly selected from R and integer s is randomly selected from S, what is the probability that rs = r?
I know i am wrong but kindly do explain why cant i read the statement above as R and S both contain Three distinct positive integers.
R = {a, b , c}
S = {p, q, r}
Is it because its not explicitly mentioned that there is no overlap?
Sorry, but I don't understand your questions at all...
Sorry i had a mistake in my last post...Why cant i Assume that
R = {r, a, b}
S = {s, c, d}
Where a,b,c,d,r,s are all distinct?
If that is the case then
We have to check if s= 1
A - s(r-1) = 0 s cant be zero so r is 1.. If r is 1, s cant be one as all are distinct - Sufficient
B - r + s = 2 1/9 Impossible hence insufficient?
