The daily production of a company is modeled by the function p = -w2 + 75w - 1250
The daily profit (p), is dependent on the number of workers (w) present.
If p = 0, the company does not lose or make any profits. This is called breaking even.
What is the GREATEST number of workers that can be present each day in order
to break even? (If necessary, round to the nearest whole number.)

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
