Question

X~bin(4,0.6)

Probability of x = 0

Answer 1

I used the \[P(X = x) = \left(\begin{matrix}n \\ x\end{matrix}\right)p^{x}(1-p)^{n-x}\]
Where p = probability of success
n = number of trials

Answer 2

So according to this, if x = 0, I should get 0.01024. But the answer is 0.0256

Answer 3

I hate myself
