Probability of giving all correct answers
Probability that at least one of them is correct
Probability that two of them is correct
Probability that all of them is correct
So, Required probability

Answer:
d). Even and odd
Explanation:
2x^3 = even
Since any number times 2 will be even
3x^2 = even/odd
Let’s assume x = 2
Then 3(2)^2 = 3 x 4 = 12 = even
Assume x = 3
3(3)^2 = 3 x 9 = 27 = odd
Now we know our equation has:
even + even/odd = even and odd
Ex: 2 + 2 = 4 = even
Ex: 2 + 3 = 5 = odd
So our equation can be equal to either even and odd
(3x+2)+(4x+1)+(2x+1)=180
9x+4=180
9x = 45
X= 5
