Answer:
12x+3y+3
Step-by-step explanation:
Let's simplify step-by-step.
4x+2y+6+7x+3y−4+x−2y+1
=4x+2y+6+7x+3y+−4+x+−2y+1
Combine Like Terms:
=4x+2y+6+7x+3y+−4+x+−2y+1
=(4x+7x+x)+(2y+3y+−2y)+(6+−4+1)
=12x+3y+3
Answer:

Step-by-step explanation:
Let the event of raining on a day be success.
Then probability of success, 
So, probability of failure is not raining on a day and is given as,

Now, number of days to check the probability of rain, 
Now, probability of raining at most one day means number of success is either 0 or 1.
Using Bernoulli's distribution for 

Therefore, the probability of at most one day of rain during the next three days is
