Answer:

1214

Step-by-step explanation:

[tex]\sf Probability\:of\:an\:event\:occurring = \dfrac{Number\:of\:ways\:it\:can\:occur}{Total\:number\:of\:possible\:outcomes}[/tex]

Total number of pizzas sold last week:

= 311 + 250 + 175 + 191

= 927

[tex]\sf \implies \textsf{Probability of selling thick crust pizza} = \dfrac{250}{927}[/tex]

[tex]\begin{aligned}\sf \implies \textsf{Expected value}& = \textsf{probabilty} \times \textsf{number}\\ & = \sf \dfrac{250}{927} \times 4500\\ & =\sf 1213.592233 \dots\\ & = \sf 1214\:(nearest\:whole\:number)\end{aligned}[/tex]

Answer:

1214

Step-by-step explanation:

311+250+175+191 = 927

then he sold 250 thick crust out of a total of 927 pizza crust

let x be the number of the thick crust expected to be sold out of the next 4500 pizza crust

Thick crust —————>  Total

 250          —————>   927

   x             —————>  4500

we have to solve this equation:

[tex]\frac{x}{250} =\frac{4500}{927}[/tex]

[tex]\Longrightarrow x=\frac{250\times 4500}{927}[/tex]

[tex]\Longrightarrow x = 1213.59223300971[/tex]
