It needs to be cooked for 20 minutes per lb plus an extra 15 minutes. What is the total cooking time?

Tx20+15

Step-by-step explanation:

t is how many times how ever many pounds it is times 20 plus the 15

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
