Hello everyone, this is probably really easy. I'm revising for my Maths exam tomorrow on data handling and I have this question that I can't seem to get the hang of
"A cube is drawn at random and replaced 250 times, how many times would you expect a red cube to have been drawn?"
The probability for picking a red cube is apparently 0.35
I assumed it was roughly a quarter so I tried doing 250 / 3 and still not the answer I was looking for.
Can someone help me understand this?
thanks a lot.
