Each number from 1 through 20 is written on a separate index card and placed inside a box. Which fraction in simplest form represents the probability that an index card with a number greater than 12 is chosen on the first attempt? a
1/20
b
2/5
c
9/20
d
3/5

since there are 8 chances that it will be greater than 12 u have to find out what percent 8 is of 20 that would make the probability 40 % then u convert 40%to a fraction and simplfy it which would make ur answer 2/5 so answer )b

The answer would be B 2/5
