Professor- I ran this brute force with straight binomial calculations on Python with N=70. I was able to reproduce 0.0984 from your work, and with brute force computation I got 0.1128.

Lots of confusion because you calculated a mean of 61.25 but then used 61.75 in the Zscore calculation. With 61.75 you get Zscore of 1.29 however this is different with mean of 61.25

I'm trying to understand how the histogram was created and exactly what it represents. Neither the open intro textbook nor this video explain that so I feel like I'm missing a pretty important stepping stone to understanding this topic.
