The probability that Alysha will miss school today is 0.15. The probability that Carla will miss school today is 0.07. The probability that both of these students will NOT miss school today is what?
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
To find the probability that both Alysha and Carla will not miss school today, we can use the concept of complementary probability.
The complementary probability is the probability of an event not happening. In this case, it is the probability that both Alysha and Carla do not miss school today.
First, let's calculate the probability that Alysha misses school, which is given as 0.15. This means the probability that she does not miss school is 1 - 0.15 = 0.85.
Similarly, the probability that Carla misses school is given as 0.07. This means the probability that she does not miss school is 1 - 0.07 = 0.93.
Now, to find the probability that both Alysha and Carla do not miss school, we can multiply their respective probabilities:
0.85 * 0.93 = 0.7905
So, the probability that both Alysha and Carla will NOT miss school today is 0.7905 or approximately 0.79.
