Answer:

The percentage of visitors who are truthful clickers and answered yes is 15%.

Step-by-step explanation:

Denote the events as follows:

<em>Y</em> = a visitor clicked Yes.

<em>N</em> = a visitor clicked No.

<em>R</em> = a visitor is a random clicker.

<em>T</em> = a visitor is a truthful clicker.

Given:

P(Y) = 0.65\\P(N) = 0.35\\P(Y|R) = 0.50 = P (N|R)\\P (R) = 0.30\\P (T) = 1 - P (R) = 1- 0.30 =0.70

The law of total probability states that:

P(A)=P(A|B)P(B)+P(A|C)P(C)

The probability of Y can be computed using the law above asP(Y)=P(Y|R)P(R)+P(Y|T)P(T)\\

Compute the value of P (Y|T) as follows:

P(Y)=P(Y\cap R)+P(Y\cap T)\\P(Y)=P(Y|R)P(R)+P(Y|T)P(T)\\0.65=(0.50\times0.30)+P(Y\cap T)\\P(Y\cap T)=0.65-0.15\\P(Y\cap T)=0.15

Percentage = 0.15 × 100 = 15%.

Thus, the percentage of visitors who are truthful clickers and answered yes is 15%.
