Alocal grocery store kept track of the types of items sold in 2 hours. express the ratio that compares the amount of produce sold to the total number of grocery items sold.

Step-by-step explanation:

Tracking sales in a small convenience store does not require sophisticated sales monitoring software or expensive computer equipment, although basic point of sale software can save time and prevent mathematical errors. Daily monitoring of inventory, saving sales receipts and using a simple spreadsheet may be all you need to track sales. Depending on the size of your store and foot traffic the store receives each day, tracking sales may take only an hour or so each day.

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
