toss/flip a coin

toss 表示“扔，抛，掷”；flip也有类似的意思表示“轻抛（翻面）”。而toss/flip a coin则是一种常见的做决定的方式，通常用于小事或没有明确偏好的情况下。

to decide something by throwing a coin up in the air and seeing which side is shown after it lands

掷硬币：把一枚硬币抛向空中，看硬币落地后露出哪一面来决定某事

When people have to decide between two things, they might do a coin flip. This involves assigning options to the sides of a coin, flicking it into the air, and then going with the option that lands face up.

当人们需要在两件事情之间做出决定时，他们可能会掷硬币。这包括将选项分配到硬币的两面，将硬币抛向空中，然后选择正面朝上的选项。

Let's toss a coin. Heads, we don't go; tails, we do.

让我们抛硬币吧。正面，我们不去；反面，我们去。
