150 because 6 times 5 is 30 then you multiply whats inside the square root thing so you'd get 25, 25 is a perfect square which simplifies to 5 then 5 times 30 is 150.

Answer:

Day 1: 12 is 40% and 18 is 60%

Day 2: 14 is 47% and 16 is 53%

Day 3: 13 is 43% and 17 is 57%

as for the second question, the reason why it's different for each day is probability, the probability can change with literally every movement like how hard you fling it or if there's outside interference like the wind.
