Answer:
3
Step-by-step explanation:
You see 3 since there are 3 occurrences of 20 in the tuple. (the 2 from the other answer is wrong on edge, I just finished taking this assignment and it told me the correct answer is 3)
It's not 3, It's 2.
Remember that the index of the first element is zero. Since 50 is the third element, Python returns 2.
