The logarithm of 10 to base 10 is 1
<h3>How to determine the logarithm?</h3>The given parameters are:
Base = 10
Number = 10
So, the expression is:
As a general rule;
The above means that;
When the base and the number are the same, the logarithm is 1
So, we have:
Hence, the logarithmic value is 1

P(1≤x≤3) defined the probability that the result is between 1 and 3, included. You can answer this question in two ways:
1. Sum the probabilities of good events:
From the graph, we have
So,
2. Use complementary probabilities
Asking that the result is 1, 2 or 3 is the same as asking that the result is not 4. The probability that the result is 4 is 0.16, so the probability that the result is not 4 will be
The result is obviously the same.
