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]
