Answer:
A.) With replacement = 1/27
B.) Without replacement = 2/91
Explanation:
Given the following :
Red marbles = 10
Blue marbles = 5
Probability that all 3 marbles are blue;
A.) With replacement :
Total no marbles = 10 + 5 = 15
P(First pick equals blue) = 5/15 = 1/3
P( second pick equals blue) = 5/15 = 1/3
P( third pick equals blue) = 5/15 = 1/3
P(blue blue blue) = (1/3) × (1/3) × (1/3) = 1/9
B.) Without replacement :
P(First pick equals blue) = 5/15 = 1/3
P( second pick equals blue) = 4/14
P( third pick equals blue) = 3/13
P(blue blue blue) = (1/3) × (4/14) × (3/13 )
= 12/546 = 2/91
Answer:
actor-observer discrepancy
Explanation:
Actor-observer discrepancy: In social psychology, the term actor-observer discrepancy or bias is defined as an individual's propensity to attribute his or her actions to some external causes whereas he or she attributes the other person's behavior or actions to some internal causes.
It is considered as a form of attributional bias that leads to develop the way an individual interacts or perceive the other person. It generally covers others and one's behavioral attributions.
In the question above, the given statement is referred to as actor-observer discrepancy.
We measure follower attitude of a leader with the help of questionnaires and interviews. These attitudes are a common indicator of leader effectiveness.
Follower perception, or follower attitude of a leader's behavior is important to be examined because followers have certain expectations of their leaders. If the leader is able to meet these expectations only then will the followers respect the leader and offer him or her trustworthiness and authority.
A follower has the ability to strengthen the leader by supporting him or her and by contributing to the organization in such areas which complement the position of the leader.

I think the term you're looking for is 'intersection'
The answer is: C. Unlike fixed interval reinforcement schedules, with variable interval reinforcement schedules, the time between a behavior and the following consequences varies around a specified average.
When the researchers conduct a fixed interval reinforcement schedules , the reward for a certain behavior would be given after a specific amount of time has passed.
When they conduct variable interval reinforcement schedules, the reward will be given within unpredictable time frame. Because the reward time is unpredictable, there is no expectation between the subject after the subject did the desired behavior. This will make the time between a behavior and the following consequences varies around a specified average depending on the subject's characteristic.
