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.
