They might be the same region but even in the same region you can get very different answers like when using sin cos and tan

dw:1360002853031:dw The diagram shows the outcomes of tossing 1 coin, 2 coins and 3 coins. There are 2 outcomes for 1 coin, 4 outcomes for 2 coins and 8 outcomes for 3 coins. Can you make the correct choice of expression now?

kropot72Best ResponseYou've already chosen the best response.1
Try substituting in each of the choices for 3 coins and see which gives the correct number of possible outcomes. For example choice B: x + x = 3 + 3 = 6 Therefore choice B is incorrect.
