The probability of happening an event P is 0.8 and the probability of happenThe probability of happening an event P is 0.8 and the probability of happening an event R is 0.9,then what is the probability of happening neither of the events?
The probability of happening an event P is 0.8 and the probability of happen
The probability of happening an event P is 0.8 and the probability of happening an event R is 0.9,then what is the probability of happening neither of the events?
The probability of happening an event P is 0.8 and the probability of happenThe probability of happening an event P is 0.8 and the probability of happening an event R is 0.9,then what is the probability of happening neither of the events?
P的发生几率是0.8 (80%),R的发生几率是0.9(90%),问两事件都不发生的几率是多少?
P的发生几率是80%,不发生几率就是20%
R的发生几率是90%,不发生就是10%
如果要两个事件都不发生,便计 20% x 10% = 2% (0.02)
