None, since that would imply that in 18 cases the coin did not show heads or tails!
Was the outcome of getting heads or tails in the 20 tosses same as the probability ratio?
It depends on what variable the probability ratio was for! The random variable could have been the number of heads minus the number of tails, for example.
What are the chances you are going to toss 2 pennies 20 times how many times do you expect the 2 pennies will come up 2 heads?
Each time you toss two pennies, there are four ways they can land: H H H T T H T T One of the four ways is (Heads - Heads), so the probability of 2 heads is 1/4 or 25% . If the pennies are 'fair' (not loaded), and you toss them a large number of times, you should expect 2 heads roughly 1/4 of the time. Out of 20 tosses, that's 5 times. But don't bet on it.

None, since that would imply that in 18 cases the coin did not show heads or tails!
How many times would a coin have to show heads in 50 tosses to show an experimental probability of 20 percent more than the theoretical probability of getting heads?
Theoretical probability = 0.5 Experimental probability = 20% more = 0.6 In 50 tosses, that would imply 30 heads.
Was the outcome of getting heads or tails in the 20 tosses same as the probability ratio?
It depends on what variable the probability ratio was for! The random variable could have been the number of heads minus the number of tails, for example.
