Parity tells you whether a given value is even or odd.

「奇偶性」能告诉，被给定的值是奇数还是偶数。

If you actually then said, oh, this is a binomial distribution, so the probability that our random variable equals some given value, k.

如果真的说， 哦，这是二项分布，所以我们的随变量等于某给定值 k 的概率。

It can only happen if the frequency of the light rays is equal to or greater than a given value — known as the threshold frequency — of the metal.

只有当光线的频率等于或大于金属的给定值（称为阈值频率）时，生这种情况。

That if I do enough trials that over large samples, the trials would kind of give me the numbers that I would expect given the expected value and the probability and all that.

如果我对大样本进行足够多的试验，这些试验给我些数字， 这些数字是我在给定预期值和概率的情况下所期望的。

In normal, finite settings, like rolling a die or drawing a card, the probability that a random value falls into a given collection of possibilities is simply the sum of the probabilities of being any one of them.

在正常的有限设置中， 例如掷骰子或抽牌，随值落入给定可能性集合的概率只是其中任何概率的总和。
