The correct answer is Choice D: 68%.
You have to make a tree diagram with all of the possibilities.
Here are the possibilities:
Rain - Win = 0.6 x 0.8 = 0.48
Rain - Loss = 0.6 x 0.2 = 0.12
No Rain - Win = 0.4 x 0.5 = 0.2
No Rain - Loss = 0.4 x 0.5 = 0.2
Adding up the two winning options gives us 68%
0.48 + 0.2 = 0.68
