Consider $A_n$ the event that this happens the $n^{\text{th}}$ time.

You want $P(A_1 \cap A_2 \cap A_3 \cap A_4)$. If the events are independent (that is to say that the probability of happening stays still, even if it already happened), this equals to :

$P(A_1) \cdot P(A_2) \cdot P(A_3) \cdot P(A_4)=(0.159)^4$

Do you understand ?
