Ben has to choose a red, white, or blue hat. he also has to choose a red, white, blue, or green shirt. finally, he must choose black, gray, or navy pants.
1) how many different outfits are possible for ben to choose?
2) what is the probability that ben randomly selects an outfit without any red in it? provide this answer as a simplified fraction or in lowest terms.

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
