The probability any one system works is 0.99
So the probability of any one system failing is 1-0.99 = 0.01, so basically a 1% chance of failure for any one system
Multiply out the value 0.01 with itself four times
0.01*0.01*0.01*0.01 = 0.000 000 01
I'm using spaces to make the number more readable
So the probability of all four systems failing is 0.00000001
Subtract this value from 1 to get
1 - 0.00000001 = 0.99999999
The answer is 0.99999999 which is what we'd expect. The probability of at least one of the systems working is very very close to 1 (aka 100%)
Answer:
Step-by-step explanation:
The master chief has three and a half cookies i.e. 
numbers of cookies.
Again the arbiter has five and three quarters of a cookie i.e. 
number of cookies.
Therefore, in total there are 
numbers of cookies.
If we divide the total number of cookies in to equal parts and distribute to then then each of them will get 
numbers of cookies. (Answer)
