,
• 3 choices of sauce
,

The total possible choices are:
![4*3*4=48](https://img.qammunity.org/2023/formulas/mathematics/college/eezmcbft7rt7yjj33jg8cp68armg0uy6p3.png)
Since only raspberry sauce can be used, the available choice becomes:
![4*1*4=16](https://img.qammunity.org/2023/formulas/mathematics/college/ws7jquvixab7h6x0lzjkhit6mjkmil3ruk.png)
Therefore, the probability that Laura's sundae will have raspberry sauce is:
![\begin{gathered} =(16)/(48) \\ =(1)/(3) \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/xwxhequ2io3xhja6b0j8oaue0lm239mz08.png)
