Question

Chaos Elementals have a 1/400 chance to drop a rare item (0.25) What is the amount of times I have to defeat these things before I should be able to get the item? (Trying to get the RoD in Terraria)

Answer 1

To obtain the rare item from Chaos Elementals in Terraria, on average you will need to defeat them about 4 times.

Step-by-step explanation:

To calculate the amount of times you need to defeat Chaos Elementals in order to obtain the rare item, you can use the concept of probability. The probability of obtaining the rare item in a single defeat is 1/400 or 0.25%. To find the expected number of defeats needed to obtain the item, you can use the formula 1/p, where p is the probability. In this case, the expected number of defeats needed is 1/0.25 = 4.

So, on average, you would need to defeat Chaos Elementals about 4 times in order to obtain the rare item. However, it's important to remember that probability is a measure of likelihood and not a guarantee. It is possible to get the item in fewer or more defeats than expected.
