Coin Magic Tricks Easy

How do I solve this math problem?
I'm looking for the right technique that solves these problems. A special coin has been created to a magic trick. The probability of landing on the head is 0.25 and 0.75 in the queues. Find the probability of throwing three heads in a row, they found that the probability launched exactly two heads in three pitches. Find the probability of delivering at least two heads in three pitches. What is the correct way to do this, Im not only trying to fool find out the steps to make these easier.
It's probability of getting three heads in a row is the problem 0.25×0.25×0.25 = 0.0156 of getting exactly 2 is 0.25×0.25×0.75 (is the probability that the third release isn't a head) and all they need is true that is why they eventually multiply = 0.0469 problems of getting at least two heads is 0.25×0.25 = 0.0625
