Step-by-step explanation:
<u><em>Step(i):-</em></u>

( 36 + 6√12 -6√12 -(√12)²)
= ( 36 -12)
= 24
c) (
<u><em>Step(ii):- </em></u>
Given that the binomial expression
(
Multiply
= 9 - 3√8 + 3√8 -(√8)²
= 9 - 8
= 1

<span>As restaurant owner
The probability of hiring Jun is 0.7 => p(J)
The probability of hiring Deron is 0.4 => p(D)
The probability of hiring at least one of you is 0.9 => p(J or D)
We have a probability equation:
p(J or D) = p(J) + p(D) - p(J and D) => 0.9 = 0.7 + 0.4 - p(J and D)
p(J and D) = 1.1 - 0.9 = 0.2
So the probability that both Jun and Deron get hired is 0.2.</span>
The answer is: 2y^2-20y+12
