Answer:
Below.
Step-by-step explanation:
Total marbles = 16
(a) Replacing the first marble:
Probability = 5/16 * 3/16
= 15/256
Not replacing the first marble:
Probability = 5/16 * 3/15
= 5/16 * 1/5
= 5/80
= 1/16.
Comparing the 2 values:
Probability of Not replacement / Replacement = 1/16 / 15/256
= 256 / 15* 16
= 16/15
Thus you are 16/15 = 1.0667 times more likely to pick a blue then a red when you do not replace the first marble.
