consider the experiment below using population s. we define two discrete random variables, x the numeric value of a randomly drawn circle and the indicator variable y that equals 1 if the selected circle is shaded, and 0 if it is not shaded. a. consider x, the numerical value on the circle. if the circles are equally likely to be chosen (say after shuffling), then in a large number of experiments (i. e., shuffling and drawing one of the ten slips), summarize the probabilities of possible outcomes using a probability density function. b. given a joint probability density function, find the marginal distributions for

1. a

2. a

3. c

4. d

6. b

there are all your answers!

hope this : )

the answer to the question is punishment. or more specifically, positive punishment.

positive punishment occurs when a behavior is given a negative consequence for the individual doing the behavior.

sara no longer wants to ask questions (the behavior) because she is ridiculed by mr. smith (the punishment).

reinforcement is inaccurate because reinforcement always gives positive consequences for the individual doing the behavior, be it by introducing a pleasant consequence or removing an unpleasant one.

it will give you a job and will make you a better person in the future! : )
