Answer:
The answer is below
Explanation:
Probability distribution are statistical function that shows all the possible outcomes of a random variable within a given range of values.
a) The mean (
) of a probability distribution of a discrete random variable is:
![\bar x=\Sigma\ [xP(x)]](https://tex.z-dn.net/?f=%5Cbar%20x%3D%5CSigma%5C%20%5BxP%28x%29%5D)
= (0 * 0.8) + (1 * 0.15) + (2 * 0.04) + (3 * 0.01) = 0.26
b) The standard deviation (σ) of a probability distribution of a discrete random variable is:
![\sigma=\sqrt{ \Sigma\ [(x-\bar x)^2*P(x)]}\\\\\sigma=\sqrt{(0-0.26)^2*0.8+(1-0.26)^2*0.15+(2-0.26)^2*0.04+(3-0.26)^2*0.01} \\\\\sigma=0.577](https://tex.z-dn.net/?f=%5Csigma%3D%5Csqrt%7B%20%5CSigma%5C%20%5B%28x-%5Cbar%20x%29%5E2%2AP%28x%29%5D%7D%5C%5C%5C%5C%5Csigma%3D%5Csqrt%7B%280-0.26%29%5E2%2A0.8%2B%281-0.26%29%5E2%2A0.15%2B%282-0.26%29%5E2%2A0.04%2B%283-0.26%29%5E2%2A0.01%7D%20%5C%5C%5C%5C%5Csigma%3D0.577)
Answer:
The correct answer is D. increase; decrease.
Explanation:
Speculation consists of the purchase (or sale) of goods with a view to their subsequent resale (repurchase), when the reason for such action is the expectation of a change in the prices affected with respect to the dominant price and not the gain derived from its use, or of some kind of transformation carried out on these or of the transfer between different markets.
A speculative operation seeks not to enjoy the good or service involved, but to obtain a benefit from the price fluctuation based on the theory of arbitration. In an extensive sense, every form of investment that a medium entails is speculative; However, the term is usually applied to that investment that does not entail any kind of commitment to the management of the assets in which it is invested, and is limited to the movement of capital (financial market), usually in the short or medium term.
The speculation is based on the forecast and the perception, so that the speculator can also be wrong if he does not correctly anticipate the evolution of future prices, so he will have to sell cheap something he bought expensive. The speculative market therefore rewards those who know how to predict.

Answer:
$600 loss
Explanation:
A call option is defined as a contract that exists between ba buyer and seller of a call option to exchange securities held at a particular price within a specific period.
To calculate the profit realised on the investment
Profit from call option= (150- 139) * 100
Profit from call option= $1,100
Profit from premium= 17 * 100
Profit from premium= $1,700
Profit on investment= Profit from call option - Profit from premium
Profit on investment = 1,100 - 1,700 = -$600
So there is a loss of $600
