I assume the trouble with this is the > instead of an =.
If this is the case, just pretend like it is an equals and solve normally with one extra rule in mind. Any time you multiply or divide by a negative remember you need to flip the sign. For instance:
-3 < -1
Multiply by 2
-6 < -2
Multiply by -2
12 > 4
The reasoning behind this is simple, while x may be bigger than b, -x is smaller than -b because x has a greater absolute value.
Answer:
Two players of equal skill level each played one game a day for 50 days and their skill level did not change from day to day.
Step-by-step explanation:
(A) The probability of player winning the game depends on the skill level . If skill level increases the probability to win also increases. The probability of success (win) must remain constant for every trial (condition of binomial distribution), hence, this case cannot be modeled by a random binomial probability.
(B) Different skill levels means the probability of success differs between players, the probability of winning each game would differ between players, hence. X can not be a binomial random variable.
(C) Same explanation as B
(D) As both players have same skill set throughout the game, the probability of winning each of the n = 100 games is the cosnat; hence, X can be modeled as a binomial random variable
(E) Same explanation as B and C
