今天針對(duì)新版gre數(shù)學(xué)復(fù)習(xí)，小編給大家整理的是關(guān)于Multiple Times的相關(guān)內(nèi)容，這些概念在考試中一定會(huì)考到的。希望考生能再接再厲，取得一個(gè)好成績(jī)，突破新版gre數(shù)學(xué)難的困境。

Multiple Times

If probability of an event happening is p, then the probability that the event happens n times in a row is p∧n.

Example:

The probability that a coin toss results in head is 0.5. Then the probability that when the coin is tossed twice, both of them are head is 0.5∧2=0.25.

Probability that a roll of a six-sided die land with face 1 is 1/6. Then the probability that 1 will turn up three times in a row is (1/6)∧3.

Remember:

Note that probability of the event happening does not change from trial to trial.
