Answer:
1.4% of connectors fail during the warranty period.
Step-by-step explanation:
We have these following probabilities:
A 90% probability that a connector is kept dry.
A 10% probability that a connectors is wet.
If a connector is dry, an 1% probability of failling.
If a connector is wet, a 5% probability of failling.
What proportion of connectors fail during the warranty period?
This is 1% of 90% and 5% of 10%. So

1.4% of connectors fail during the warranty period.

Answer:
3(3+x)=9+3x, or B
Step-by-step explanation:
From the diagram, we can see that there are 3 rows of one x and 3 ones each.
Therefore, we can make the equation 3(3+x)
Then we could either count the blocks out to get 9+3x or just solve the above equation.
So, the answer would be 3(3+x)=9+3x, or B
