Ok, so, i have a total of 9... let's say "units" there is a 10% chance that something happens per unit
what is the chance of getting three 10% chances in a row happening, with 9 total rolls

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2

98%
