CFA考試要考數(shù)學(xué)知識(shí)？有沒(méi)有提高數(shù)學(xué)方法？

在CFA考試中也是要考數(shù)學(xué)的，在上學(xué)的時(shí)候你對(duì)CFA考試頭疼嗎？如果你正在準(zhǔn)備考CFA考試，這不小編給你送了一道概率相關(guān)的考題，看看你能不能做對(duì)呢？

Compared to investing in a single security, diversification provides investors a way to:

A  increase the expected rate of return.

B  decrease the volatility of returns.

C  increase the probability of high returns.

【答案以及解析】B Diversification provides an investor reduced risk. However, the expected return is generally similar or less than that expected from investing in a single risky security. Very high or very low returns become less likely.

【核心詞匯】probability ：概率 是指對(duì)隨機(jī)事件A發(fā)生的可能性大小的度量（數(shù)值），記做P(A)。
