Let the random variable x be the outcome of rolling a 6-sided die. assuming the die is fair, the probability distribution is as follows:
x 1 2 3 4 5 6
probability 1/6 1/6 1/6 1/6 1/6 1/6
using the above table to answer the question: what is the probability that x is less than or equal to 2?
a.1/6
b.1/5
c.1/3
d.1/2
e.2/3

According to the rna world hypothesis, rna acted as the genetic material and catalyzed reactions in ancient cells. what conclusion can you draw from this?               a.  this implies that dna and proteins aren't essential in cells today.    b.  this implies that rna can catalyze any chemical reaction that enzymes catalyze.    c.  this implies that if a cell has a problem with its dna, its rna can compensate for the damaged dna.    d.  this implies that dna and proteins evolved after rna.
