<u>First Solution</u>
        -2x + y = 1
-2x + 2x + y = 1 + 2x
                 y = 1 + 2x

<u>Second Solution</u>
     -2x + y = 1
-2x + y - y = 1 - y
           <u>-2x</u> = <u>1 - y</u>
            -2       -2
              x = -0.5 + 0.5y
0.5 + x - x = -0.5 + 0.5 - x + 0.5y
           0.5 = -x + 0.5y
 -0.5y - 0.5 = -x + 0.5y - 0.5y - 0.5
   2 · (-0.5y) = 2(-x - 0.5)
                y = -2x - 1

<u>Third Solution</u>
             -2x + y = 1
        -2x + y - 1 = 1 - 1
        -2x + y - 1 = 0
-2x + 2x + y - 1 = 2x
                 y - 1 = 2x
           y - 1 + 1 = 2x + 1
                      y = 2x + 1

This year the CDC reported that 30% of adults received their flu shot. Of those adults who received their flu shot,
Vlad [161]

Using conditional probability, it is found that there is a 0.1165 = 11.65% probability that a person with the flu is a person who received a flu shot.

Conditional Probability

P(B|A) = \frac{P(A \cap B)}{P(A)}

In which

  • P(B|A) is the probability of event B happening, given that A happened.
  • P(A \cap B) is the probability of both A and B happening.
  • P(A) is the probability of A happening.

In this problem:

  • Event A: Person has the flu.
  • Event B: Person got the flu shot.

The percentages associated with getting the flu are:

  • 20% of 30%(got the shot).
  • 65% of 70%(did not get the shot).

Hence:

P(A) = 0.2(0.3) + 0.65(0.7) = 0.515

The probability of both having the flu and getting the shot is:

P(A \cap B) = 0.2(0.3) = 0.06

Hence, the conditional probability is:

P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.06}{0.515} = 0.1165

0.1165 = 11.65% probability that a person with the flu is a person who received a flu shot.
