Answer:
1/3
Step-by-step explanation:
In math, to find the probability of an event we need to take the total amount of favorable outcomes and divide this number between the total amount of possible outcomes.
In this case Paul has 15 T-shirts and he takes one of his <u>blue</u> T-shirts at random. We can see that he has a total of 3 blue shirts, thus, the total amount of possible outcomes is 3.
Now, we need to find the probability that the T-shirt is light blue, he only has 1 light blue t-shirt so the number of favorable outcomes is 1.
If we divide the number of favorable outcomes between the number of possible outcomes we have . Thus, the probability that the T-shirt is light blue is 1/3

Answer:
a = 8
b = -8
Step-by-step explanation:
You have the following function:
A function is differentiable at a point c, if the derivative of the function in such a point exists. That is, f'(c) exists.
In this case, you need that the function is differentiable for t=2, then, you have:
If the derivative exists for t=2, it is necessary that the previous derivatives are equal:
Furthermore it is necessary that for t=2, both parts of the function are equal:
Then, a = 8, b = -8
