Find an expression for the general term of each of the series below. use n as your index, and pick your general term so that the sum giving the series starts with n=0. a. x5ex2=x5+x7+x92! +x113! +⋯ general term = b. x5cosx2=x5−x92! +x134! −x176! +⋯ general term

a)

b)

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
