I think we need more information or assumptions? Terrorists are not arrested at random.
Perhaps there were only 83 terrorists in the 1000 population and all have been arrested. Then p = 0.
Perhaps all 1000 are terrorists and only 83 have been arrested so far. Then p = 1.
So, probably the answer is somewhere between 0 and 1.

There is no proportion presented for the ethnic group compared to the pool from which terrorists are drawn, beyond the simple assertion they are a "minority."

The Venn diagram given thus far is an unknown size population with two subsets and an overlap region. The overlap is stated as 83/100 terrorists belong to ethnic group, and so the remainder (17/100 terrorists) belong to the external slice of terrorists that are not members of the ethnic group.

But there is no specification of the proportions for ethnic group, as in what proportion of the ethnic group are also members of the terrorist group.

Less is more. Stay pure. Stay poor.
The bigger question, how old is you kid and you couldn't find a baseball example? I would make sure their teacher isn't a white nationalist or xenophobia. Trump is this you?

All kidding aside, this doesn't feel like the original question, or it was written poorly. For example "next' isn't linked to anything. Please double Check the original question.
