(二)甲自民國 90 年 3 月 1 日起任職適用勞動基準法 A 公司，該公司未經預告即於民國 98 年12 月 31 日下班將其資遣，甲每月平均工資為新臺幣30,000 元，請問 A 公司應給付甲之資遣費及預告工資金額各為多少？(計算至小數點後第 2 位，以下四捨五入)

一、A finance PhD program recruits new students by two ways: Choosing the good-grade postgraduates (Inner Promotion, IP), or by opening exam competition (Open Competition, OC). $P(IP) = 0.4$, $P(OC) = 0.6$. After the first year qualification test, there are 90% IP and 75% OC students passed. If you randomly select a test-passed student, what is the probability the student recruited from IP? (10 %)

二、A mayor wants to know whether there exists seasonal differences about the visitors travelling to his city. He selects 1360 passengers and surveys their arrival time: | Season | Spring | Summer | Autumn | Winter | | --- | --- | --- | --- | --- | | Numbers | 334 | 371 | 327 | 328 | Please use Chi-square test under the significant level $\alpha=0.01$. (13%) | $\chi^2_\nu(\alpha)$ | | | | | | | --- | --- | --- | --- | --- | --- | | $\alpha$ | | | | | | | $\nu$ | .10 | .05 | .025 | .01 | .005 | | 1 | 2.706 | 3.843 | 5.025 | 6.637 | 7.882 | | 2 | 4.605 | 5.992 | 7.378 | 9.210 | 10.597 | | 3 | 6.251 | 7.815 | 9.348 | 11.344 | 12.837 | | 4 | 7.779 | 9.488 | 11.143 | 13.277 | 14.860 | | 5 | 9.236 | 11.070 | 12.832 | 15.085 | 16.748 |

三、You participate a game by throwing a coin, which will be HEAD with P(H)=0.6 and TAIL with P(T)=0.4. The throwing results are independent. In the beginning, you own 5 dollars. If you throw a HEAD, you can get 1 dollar; however, if you throw a TAIL, you lose 1 dollar. This game will end when you own 15 dollars or lose all the money. What is the probability you own 15 dollars and lose all the money respectively? (12 %)

四、Two independent random variables X and Y. Y follows standard normal distribution, and X is uniform between [0,1]. $Z = X + Y$. Please derive the detail process that $cov(X, Z) = var(X)$. (15%)

五、Suppose $X_1, X_2, \ldots, X_n$ are independent random variables and follow Poisson distribution with mean $\lambda$. Please use moment generating function to show that $\overline{X} = \sum X_i / n$ converges in probability to $\lambda$. (Hint: The distribution of $\overline{X}$ degenerates to a constant random variable.) (10%)

六、Suppose $X_1, X_2, \ldots, X_{10}$ are independent random variables and follow N(0, 1). Let $S = X_1+X_2+X_3+X_4+X_5$ and $W = X_6^2+X_7^2+X_8^2+X_9^2+X_{10}^2$. What is the probability $P(S/\sqrt{W} > 4.0324)$? (Rounded to third place.) (10%)

七、An urn contains six balls, one marked WIN and five marked LOSE. You and another player take turns selecting a ball from the urn, one at a time. The first person to select the WIN ball is the winner. If you draw first, find the probability that you will win (a) When the sampling is done with replacement. (10%)

(b) When the sampling is done without replacement. (5%)

八、Bowl B₁ contains 2 white chips, bowl B₂ contains 2 red chips, bowl B₃ contains 2 white and 2 red chips, and bowl B₄ contains 3 white chips and 1 red chip. The probabilities of selecting bowl B₁, B₂, B₃, or B₄ are 1/2, 1/4, 1/8, and 1/8, respectively. A bowl is selected using these probabilities, and a chip is then drawn random. Find (a) \(\mathrm{P}(\mathrm{W})\) , the probability of drawing a white chip. \((10\%)\)

(b) \(\mathrm{P(B_1|W)}\), the conditional probability that bowl \(\mathrm{B}_1\) had been selected, given that a white chip was drawn. (5%)
