Hello,

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 ?
