文本左对齐和居中对齐

Question

我该如何纠正对齐

\begin{align*}
    &1 \text{ stg } = 0.5 \quad 
    P(A \mid A) = a \quad 
    P(B \mid B) = b \\
    &P(B \mid A) = (1-a) \quad 
    P(A \mid B) = 1-b
\end{align*}

我希望“1 stg = 0.5”位于同一行但左对齐

Answer 1

可能你想要的是类似这样的东西：

\documentclass{article}
\usepackage{amsmath}

\begin{document}

\begin{equation*}
1\,\text{stg} = 0.5 \qquad
\begin{alignedat}[t]{2}
    P(A \mid A) &= a     &\qquad P(B \mid B) &= b \\
    P(B \mid A) &= (1-a) &\qquad P(A \mid B) &= 1-b
\end{alignedat}
\end{equation*}

\end{document}
