单选题 An analyst gathers the following information about the odds of two companies raising new stock.
Company Odds
1 3 to 5
2 4 to 7
If the companies' actions are independent, the probability that both companies will issue debt is closest to.
A. 0.136
B. 0.171
C. 0.343

【正确答案】 A
【答案解析】[解析] 几率(odds)等于事情发生的可能性除以事情不发生的可能性，P1=3/(3+5)=0.3750，P2= 4/(4+7)=0.3636，所以两个独立事情一起发生的概率为P1×P2=0.3750×0.3636=0.136。
