Answer-

The correct option would be-

Given that the program was targeted at adults, there is a 37.5% chance that it was recorded.

Solution-

We know that, probability of A given that B is,

$P(A|B)=\dfrac{P(A\ \cup\ B)}{P(B)}$

From the table,

$P(\text{Recorded})=0.417\\\\P(\text{Adult}) = 1\\\\P(\text{Recorded}\ |\ \text{Adult})=0.375$

Probability that the program was recorded given that the targeted audiences were adults is,

$P(\text{Recorded}\ |\ \text{Adult})=\dfrac{P(\text{Recorded}\ \cup\ \text{Adult})}{P(\text{Adult})}$

$\dfrac{0.375}{1}=0.375=37.5\%$

Probability that the targeted audiences were adults given that the program was recorded is,

$P(\text{Adult}\ |\ \text{Recorded})=\dfrac{P(\text{Adult}\ \cup\ \text{Recorded})}{P(\text{Recorded})}$

$\dfrac{0.375}{0.417}=0.899=89.9\%$

Therefore, the first option "Given that the program was targeted at adults, there is a 37.5% chance that it was recorded." is correct

Solve the equation: 2+3x=4+x(2+x)

grandymaker [24]

2 + 3x = 4 + 2x + x^2
x^2 - x + 2 = 0

(x - 0.5)^2 - 0.25 + 2 = 0

(x - 0.5)^2 = -1.75

x - 0.5 = +/- sqrt 1.75 * i

x = 0.5 + 1.32i , 0.5 - 1.32i answer
