Answer:
C
Step-by-step explanation:
If we know that the event will <em>definitely</em> happen, then there is no doubt and no probability that the event will <em>not</em> happen.
This means that the probability is 1, which is the same as 100%.
3 log 2x = 4
==> log 2x = 4/3
==> 2x = 10^(4/3)
==> x = \frac{10^(4/3)}{2}
Prime numbers are only divisible by 1 or itself; the first few are are 2, 3, 5, 7, and 11.
