alice wins if a total of 5 is rolled. finn wins if a total of 9 is rolled.

percentage - 25%

probability - 0.25

we know,

total boys = 10

total girls = 10

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

probability of choosing a girl with glasses is =

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
