Question 1197501: An electronic system has four components labeled as 1, 2, 3, and 4. The system has to
be used during a given time period. The probability that component 𝑖 will fail during
that time period is 𝑓𝑖
for 𝑖 = 1, … , 4. Failures of the components are physically
independent of each other. A system failure occurs if component 1 fails or if at least
two of the other components fail. Specify an appropriate sample space and determine
the probability of a system failure.

You can put this solution on YOUR website! .
what is "f i" in the third line of your post ?
Also, all numerical values are missed in the post, which looks to be suspicient.
Double check you post/(source) and re-post in clear form.
