There are 8 tosses in total. Out of those 8, there are 4 even numbers (4, 2, 6, 4). Therefore, the experimental probability of tossing an even number is:

4/8 = 1/2

So the answer is C. The fraction is one-half.

There are 20 options for selecting the captain, and once the captain is selected, there are 19 options left for selecting the co-captain (since one person has already been chosen). However, since the order of choosing the captain and co-captain doesn't matter, the total number of different ways to select the two positions is:

20 x 19 / 2 = 190

The division by 2 is because the order of selection doesn't matter. So the answer is not listed, but the closest answer is C. 380.
