If we flipped a fair coin 10 times and then 100 times, would it be more likely, less likely or the same to get 70% or more heads on 10 flips or on 100 flips? Why? If you can state both reasonings. statisticly and probability

Solution

P(7 heads on 10 flips ) = 10C7 * 0.5^10

P(70 heads on 100 flips) = 100C70 *0.5^100

1st one is more likely to occur as it has more probablity as compared to the second one.
