how likely is it that she will be late on any given day?

If Juaita bumps into Troy inthe hallway between periods2 and 3, there is a 25% chance that she will be late for class. If she does not bump into Troy, she will make it to class on time. If there is a 20% chance that juanita will bump into Troy, how likely is it that she will be late on any given day?

so 25% will be late
20% bump into Troy

I dont know what o do with these percentages =S

thanks
