Number of signatures Pat have = 160

Number of signatures Cam Pane have = 80

Solution:

Let x be the number of signatures Cam Pane had.

Number of signatures Pat Tronize had = twice of x = 2x

Total number of signatures both had = 240

Came Pane had signatures + Pat Tronize had signatures = 240

⇒ x + 2x = 240

⇒ 3x = 240

Divide by 3 on both side of the equation.

⇒ x = 80

⇒ 2x = 2(80) = 160

Hence

Number of signatures Pat have = 160

Number of signatures Cam Pane have = 80

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
