Suppose you flip a coin twice. what is the probability that you get tails on the first flip and tail on the second flip?

Probability of getting tails on the first flip: 1/2 (because it's one of two possible outcomes).

Probability of getting tails on two consecutive flips: 1/4 (because it's one out of four possible outcomes- tails tails, tails heads, heads tails, heads heads)

A simpler way of thinking about it is 1/2*1/2, because you already have 1/2 for getting tails the first time, and if getting tails the second time were an independent event then the probability would be 1/3, but since it's getting tails twice you multiply the probabilities.

Either way, the answer is 1/4 (or 25%)
