Question

Which expression would you use to find the number of outcomes for flipping 4 coins?

Answer 1

2*2*2*2
Multiply 2 by 2 by 2 by 2.

Answer 2

`2^4`.

Explanation:

If we flip a coin then we have two possibilities, i.e., head or tail. So,

Number of outcomes for flipping a coin = 2

If n coins are tossed, then the total number of outcomes is defined by the expression
`2^n`.

It is given that the number of coins is 4.

Number of outcomes =
`2^4=2* 2* 2* 2=16`

Hence, he required expression is
`2^4`.
