Transformers in the electricity distribution network have a component called a recloser, which aims to cut off the flow of electricity if there is a disturbance in the distribution network. If the recloser experiences problems, what you can do is replace it$.$ Currently there are $3$ reclosers in the warehouse.

What is the probability that this recloser will run out before $500$ hours, it is known that the reliability of the recloser is e$^(-0\mathrm{.}0001$X$*$t$^(1\mathrm{.}5))$
