Answer:
A and D
Step-by-step explanation:
Matched pairs t test is used for paired data. Data sets are "paired" when the two sets have the same number of data points and each data point in a set is related to only one data point in the other set.
A good example is before/after data. Each set has the same number of data points, and each data point in the after set is related to one in the before set.
B is not an option because, although the samples are the same size, there is not a paired relationship between the sets.
C is not an option because the samples are not the same size.

Answer: 8/9
Step-by-step explanation:
Taking the probability as
AA = 4/9 AB = 2/9 BA = 2/9 BB = 1/9
These spaces AA,AB,BA,BB is indicates who wins each game.
There is a 2/3 probability that A will win any particular game.
But considering that these events are independent events, the probability that A wins both games is 2/3 and 2/3 which equals to 4/9.
Therefore the probability that A wins at least one match would be 1 − P(BB).
And this gives 1 - (1/9) =
8/9
