In an up-and-down counting number, the digits increase to a maximum digit and then decrease. This maximum is not the first or last digit. (Example:
2S68S0 is an up-and-down number, but 25587 6 is not.) How many different
4-digit up-and-down numbers have a maximum digit of 6?

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
