Fill in the Blank Question
$20\mathrm{\%}$ of a restaurant's customers order the chef's special. 230 customers are anticipated to dine tonight at the restaurant. The expected number of chef's specials that will be ordered tonight is

Step 1 ：The question is asking for the expected number of chef's special orders for the night. Since we know that 20% of the customers order the chef's special and we are expecting 230 customers, we can calculate the expected number of orders by multiplying the total number of customers by the percentage that order the chef's special.

Step 2 ：Let's denote the total number of customers as $total\mathrm{\_}customers=230$

Step 3 ：The percentage of customers who order the chef's special is $percentage\mathrm{\_}order\mathrm{\_}special=0.2$

Step 4 ：We can calculate the expected number of orders by multiplying the total number of customers by the percentage that order the chef's special. So, $expected\mathrm{\_}orders=total\mathrm{\_}customers\times percentage\mathrm{\_}order\mathrm{\_}special=46.0$

Step 5 ：Final Answer: The expected number of chef's specials that will be ordered tonight is $\boxed{{\displaystyle 46}}$
