Probability Tossing Three Coins Tree Diagram At Least 2 Heads

Dependent Mutually Exclusive Probability: https://www.youtube.com/watch?v=vPpxiU6Be7Y&list=PLJ-ma5dJyAqpmOnjvNvj0a7JRb-JzN_yC
CORRECTION: Last option in Tree Diagram is HHH, corrected later while writing the values in the table.
However, there is a mistake in writing the solution of part c.
at the most 2 heads should have been 7/8
I should have included TTT (no Heads also)
Thanks
