Answer:
[tex] \frac{1}{256} [/tex]
Step-by-step explanation:
Your total is 4 and each one is a individual (1)
so the probability of 1 ball would be :
[tex] \frac{1}{4} [/tex]
because the question asks for the probability they are picked 4 times, we would need to multiply ¼ four times.
[tex] \frac{1}{4} \times \frac{1}{4} \times \frac{1}{4} \times \frac{1}{4} = \frac{1}{256} [/tex]
