If it takes 15 hours to travel 900 miles then it gives you the fraction 15/900 where the numerator(top number) is 15 and denominator(bottom number) is 900.

Then to simplify it: since 15 is a common factor of itself(15) and 900, 15/15 = 1(1 hour) and 900/15 = 60(60 miles).

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

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