ANSWER
0.756
EXPLANATION
Let x represent number of correct answers.
We can find
which leads us to
which uses the compliment of 
to find the probability of getting at least 2 questions correct.
Note that since 
and 
are mutually exclusive, we have
Then 
as we have 
to answer the questions incorrectly divided by the total 
to answer the questions.
Exactly 1 answer correct: 
Therefore

Since 3 1/6 is only 1/3 of what he is watering, you can multiply the 3 1/6 by 3 to find your answer
9 1/2 should be your answer.
First you multiply the whole number by 3
3x3 = 9
Now we multiply the fraction
1/6 x 3 = 1/2 because we multiply the 1 on top. 3x1 = 3 and 3/6 is reduces to 1/2
Answer:
(x + 2)²(x - 3)² = 0
Step-by-step explanation:
Since we have a degree of 2 and double of the same roots, we know that each root would have a multiplicity of 2. Therefore, our answer is(x + 2)²(x - 3)² = 0
