Question

Suppose x coins are tossed. Write an expression to represent the number of possible outcomes.
A. 2^X
B. X+X
C. X*X
D. 2X

Answer 1

so waht do you know about this already?

Answer 2

There are 2 sides to a coin

Answer 3

>.< besides that. i mean what do you know about probability?

Answer 4

I know the probability of a coin landing on heads is 1/2 the same for tails

Answer 5

and I know every time you add a coin the chance that there will only be one heads halves

Answer 6

so then you just answered your own question. what's the answer then?

Answer 7

but its talking about outcomes

Answer 8

not probability

Answer 9

-_- >.< their the same region of math. >_<

Answer 10

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

Answer 11

Im confused here

Answer 12

\[x^2\] that's the answer

Answer 13

thats not one of the answers available

Answer 14

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?

Answer 15

um maybe

Answer 16

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.

Answer 17

@bookaholic Have you tried another substitution?
