I need help/ 100 points for this please pls

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:
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]
