Answer:
The total number of marbles is 5 + 32 = 37. You select a marble 2 times.
The 1st time you pick a marble, the probability of selecting red is 5/37.
Since there is no replacement, now we only have 4 red marbles to choose from a total of 36 marbles. So the second time the probability is 4/36.
Now we multiply the 2 answers:
(5/37) * (4/36) = 0.015015, or rounded to 3 decimal places, 0.015.

Answer:
5/19
Step-by-step explanation:
P(E) =
Possible Outcomes = Red Marbles amd Green Marbles
- Red Marbles = 15
- Green Marbles = 5
=> 5 + 15 => 20 marbles
Total Outcomes = Number of total marbles
=> 15 + 20 + 5 + 16
=> 56 marbles
Therefore,
→ P (Having red or a green marble) = 20/56
=> 5/19
