2/14 or 1/7

Efrain Howell · Answer 2

1 in 6 chance or 16.6 - percent chance (17% chance rounded up)

Explanation: So first of all the probability of a girl getting called in general is a 4 in 14 chance. Or a 25% chance. We can figure this out by finding out the amount of girls, and adding it by the guys, and putting the girls as the numerator. Since half the girls wear glasses, this puts it down to 2 girls in all, simply replace the 4 with a 2 and you have a 2 in 14 chance, which simplifies to a 1 in 6 chance. Thus, the probability would be a 1 in 6 chance, or 16.6 - chance.
