Therefore, I think the probability is 14/64. Not sure so check my work.
14 combinations
64 outcomes (2+4+8+16+32+64 or 2^n)
It is close to 200 because 150 or above would be rounded to 200. Below 150 would be 100
The speed that lisa drive was a possibility of 65 mph
7/4 because you times 4 and 1.then add 3 and you get 7 so 7/4
