Solution to probability P (not O and B) = 1100/1200. But why don’t you get the same result when you calculate: P (not O and B) = P (not O) + P (B) = 500/1200 + 800/1200 = 1300/1200. Why does it come out as 1300/1200 and not 1100/1200? Thanks to!
Hello I would tick this but I'm not sure
How can I solve the number 126 with geogebra?
How do you calculate the change in value from year 01? The base year isn't given? And how can the price index be calculated? Thanks!
Task: Why do we calculate €1-€0.2 (expected value) = €0.8? Why can't we say that the player has to pay 20 cents per game for the game to be fair? Because then E(X) = 0. Thank you!
