<h2>Question Clarification:</h2>
I think there is some typing error with your question as searching it on google is showing me it is a "fill the blanks" type of question. I am attaching the actual question for clarification.
<h2>Answer:</h2>(1) Number
(2) Proportion
<h2>Step-by-step explanation:</h2>
(1) A Frequency distribution is a tabular or graphical representation of number of observations within a given interval. The size of the intervals are determined by the nature of the data being analyzed and the objectives of the analyst. The intervals are collectively exhaustive and mutually exclusive.
(2) On the other hand, a relative frequency distribution, instead of numbers, shows the proportion (percentage) of the total number of observations that belong to a certain value or a class of values

Answer:
The probability that it will choose food #2 on the second trial after the initial trial = 0.3125
Step-by-step explanation:
Given - A lab animal may eat any one of three foods each day. Laboratory records show that if the animal chooses one food on one trial, it will choose the same food on the next trial with a probability of 50%, and it will choose the other foods on the next trial with equal probabilities of 25%.
To find - If the animal chooses food #1 on an initial trial, what is the probability that it will choose food #2 on the second trial after the initial trial?
Proof -
By the given information, we get the stohastic matrix
As we know that,
The matrix is a Markov chain
Let
The initial state vector be
we choose this initial vector because given that If the animal chooses food #1 on an initial trial.
Now,
∴ we get
Now,
∴ we get
∴ we get
The probability that it will choose food #2 on the second trial after the initial trial = 0.3125
