<span>The poison distribution can be used to approximate the binomial distribution when the sample size n is large. This is then calculated using the formula
P(X) = e^-(np) *(np)^x
substituting X= 3
P(3)= e^-(430*1.5/100) * (430*1.5/100)^3
P(3)= 0.00158*268.3
P(3) = 0.42
P(3) = 0.0042%
P= probability of X occurring given n and p
n= sample size
p= true probability
e= exponential constant ~2.718
X=number of sample successes</span>

'Among the choices above, the power enjoyed by a stockholder is found in letter c " might receive dividends when the company makes a profit". A stockholder or a shareholder are individuals or companies that has a share in a profit organization. They purchase their shares and can earn in return by receiving dividends if the profit is good or by selling their shares to the company or to a co-stockholder. They may lose some if not all of their shares if ever the invested company suffers bankcruptcy.
The answer is effort justification. It is an idea as well as paradigm in the social psychology in which people who have reach the goal yet discover that it was not worth it. It is from the cognitive dissonance theory of Leon Festinger.
Answer: A- negative reinforcement trap
Explanation: By B. F. Skinner, The negative reinforcement trap occurs when a parent try to avoid a situation by engaging in a behaviour that suits the request of a child due to the child's plead or whinings. It is a type of behavior that is likely to occur in the future again because the child feels his request was granted and will always whine or cry to get his choice satisfied.
Negative reinforcement - like positive reinforcement -plays a role in maintaining behaviors that are beneficial and sometimes not. Most parents, inadvertently reinforce behaviour. For example
Maryam's mother's behavior of allowing the child leave her room dirty is negatively reinforced because she feels allowing her will make the winning stop. The child's whining is positively reinforced because she learns if she whines loud and long enough, she will be allowed to do as she pleases.
