A. 8
B. 12
C. 20
D. 100
C. 20
There are 10 styles of running shoes and each style has two versions (men's and women's). Therefore, the total number of possible outcomes is 10 x 2 = 20.
To find the total number of possible outcomes for 10 styles of running shoes, each in a men's and women's version, you need to multiply the number of options for each style. Since there are 10 styles and each style has 2 versions (men's and women's), the total number of possible outcomes is 10 multiplied by 2, which equals 20.
Therefore, the correct answer is C. 20.
