The common ratio is 2:1, or dividing by 2
X = 89
Used the Pythagorean theorem (a squared plus b squared equals c squared)
The probability that one switch fails is 1 from 10. According to this the probability is 1/10=0.1.
If you need to have only 1 switch from million to fail, this means that you need the probability 1/1000000=0.000001.
<span>In order to have this probability of one switch failing you will need 1000000 (million) switches.</span>
