Over a very large number of trials,the probability of an eve

3个回答

  • 第一句:over在..之中(参考楼上)介词

    第二句:exert a great worldwide influence over、on art

    over 和on 都可以,但是over的范围更大,表示覆盖,说明对其影响非常大,介词.

    the probability of an event's occurring= the probability that an event will occurr.

    that引导同位语从句,这里考的恰恰不是平行结构,而是避免重复.

    希望能帮到您.
