Question is from Prep Swift, “Don’t Play the Lottery”

6 different numbers

→ first pick could be from 59 total numbers

→ second pick could be from 58 total numbers (since there is no repetition and we already picked 1 from 59 numbers)

similarly, → third pick could be 57

So total ways could be = 59x58x57x56x55x54 = 32,441,381,280

Also, do let me know if my answer is correct.

No, because the order of the numbers does *not* matter in a lottery (this should have been explained in the accompanying video). Also the GRE cannot ask you to enter a number that cannot fit in its own calculator.
