Answer:
robability formula is the ratio of number of favorable outcomes to the total number of possible outcomes. Measures the likelihood of an event in the following way: - If P(A) > P(B) then event A is more likely to occur than event B. - If P(A) = P(B) then events A and B are equally likely to occur.

no it's not parallel to that.
Answer:
1. The probability that the T-shirt will be grey :-
=》
![\frac{2}{20}](https://tex.z-dn.net/?f=%20%5Cfrac%7B2%7D%7B20%7D%20)
=》
![\frac{1}{10}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B10%7D%20)
=》
![0.1](https://tex.z-dn.net/?f=0.1)
hence, the probability of grey t-shirt is 0.1
2. The probability that the T-shirt will not be red :-
=》
![1 - \frac{4}{20}](https://tex.z-dn.net/?f=1%20-%20%20%5Cfrac%7B4%7D%7B20%7D%20)
=》
![1 - \frac{2}{10}](https://tex.z-dn.net/?f=1%20-%20%20%5Cfrac%7B2%7D%7B10%7D%20)
=》
![1 - 0.2](https://tex.z-dn.net/?f=1%20-%200.2)
=》
![0.8](https://tex.z-dn.net/?f=0.8)
The probability that the T-shirt will not be red is
0.8
3. He takes one of his blue T-shirts at random.
What is the probability that the T-shirt is light blue
total blue t-shirts = 5
so, the probability of choosing light blue t-shirt is
=》
![\frac{1}{5}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B5%7D%20)
=》
![\frac{2}{10}](https://tex.z-dn.net/?f=%20%5Cfrac%7B2%7D%7B10%7D%20)
=》
![0.2](https://tex.z-dn.net/?f=0.2)
hence, the probability of choosing light blue t-shirt is 0.2
