# Math Help - Probability check

1. ## Probability check

I had an assignment and I got this part of equation:
$P^4*(1-P)^0$

Is it correct how I solved it ?
$= P^4-P^4$
remember the Power is 0

2. No matter which is $a$ is $a^{0}=1$ , so that...

3. so was it correct?

How did you obtain $P^4-P^4\;\;?$

There is a difference between

$P^4(1-P)^0$

and

$P^4\left(1-P^0\right)$
