Question

In the same scenario as 4.4, what is the lowest number of IceCream-type small monsters that a collector must capture to make capturing at least two of the same species more likely than not?

Answer 1

N = 7

Explanation:

Let the lowest number of IceCream-type small monsters that a collector must capture to make capturing two of the same species most likely than not be N

Then, we have here:

31! 1 - (31-1) > 0.5 31N

31! (31-N! <0.5 31 1 0 .5

Solving this by hit and trial,

For N = 6,

(31-611_05973 316 = 0.5973

For N = 7,

31/ (31-7 -0.4817 <0.0 317

Therefore N = 7 is the required number here.
