Today I just solved a similar (but much more complicated) problem for you under this link

https://www.algebra.com/algebra/homework/word/misc/Miscellaneous_Word_Problems.faq.question.1164119.html

Use the formula (1) from that solution

    n(A U B U C) = n(A) + n(B) + n(C) - n(AB) - n(AC) - nBC) + n(ABC)              (1)

which is valid for any three subsets A, B, C of a universal set, their in-pair intersections AB, AC and BC, and the triple intersection ABC.


Substitute all given data into the formula and obtain

    the number of tourists who visited at least one of the three parks = 273 + 266 + 298 - 94 - 75 - 56 + 33 = 645.


The complement to it,  1062 - 645 = 417  is the ANSWER  to your question.

Solved.
