Use the Ratio Test or the Root Test to determine if the following series converges absolutely or diverges.[infinity]Σ(-1)^k+1[5k^4+ k/2k^4+k+7]^k k=1A. The series diverges by the Root Test because nothing. B. The series converges absolutely by the Ratio Test because r nothing. C. Both tests are inconclusive because r nothing and nothing.

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
