Okay, hete is how to solve this problem:

Since the probability that Alysha will miss is 0.15, that means that it is 15%, right? So, the probability that Alysha will NOT miss is 100 - 15, which is 85%. So the answer is 0.85

Now for Carla. 0.07 = 7%.

100 - 7 = 93%. So the answer is 0.93.

prob(Alysha miss school AND Carla miss school) = (.15)(.07) = .0105

So prob that both will not miss school

= 1 - .0105

= .9895
