Probability of 1st chocolate = 15/30 = 1/2
Probability of 2nd after picking chocolate = 14/29

Multiply the 2 probabilities together
1/2 * 14/29 = 14/58 = 7/29

Answer:

The  probability is  P(I  | \ L ) =0.4

Yes with the additional information that the person logs on everyday the probability increased from  P(I) =  0.3  to P(I |  L )  =  0.4

Step-by-step explanation:

From the question we are told that

   The probability that the user is from outside the country is  P(O) =  0.7

    The probability that the user log on everyday is  P(L) =  0.6

    The  probability that the user log on everyday and he/she is from inside the country  is  P(L| I) =  0.80

Generally using Bayes theorem the the probability that a person is from the country given that he logs on the website every day is mathematically represented as

        P(I  | \ L ) =  \frac{ P(L|I) *  P(I)}{ P(L)}

Here P(I) is the probability that the person log on every day and it is mathematically evaluated as

        P(I)  =  1 - P(O)

          P(I)  =  1 - 0.7

         P(I)  = 0.3

So

      P(I  | \ L ) =  \frac{ 0,8 *  0.3}{ 0.6}

      P(I  | \ L ) =0.4
