The possible combinations are:
1,9
2,8
3,7
4,6
9,1
8,2
7,3
6,4
Total straws: 9
Probability of first being 1: 1/9
Probability of second being 9: 1/8
Probability of both: 1/9 x 1/8 = 1/72
This will be multiplied by 8 as there are 8 possible combinations:
8 x 1/72
= 8/72
= 1/9
Answer:
the answer should be c
Step-by-step explanation:
Answer:
aₙ = (-3) (-1)ⁿ⁻¹
limit does not exist
Step-by-step explanation:
-3, 3, -3, 3, ...
This is an alternating geometric series where the first term is -3 and the common ratio is -1. The nth term is therefore:
aₙ = (-3) (-1)ⁿ⁻¹
Since the sequence alternates between -3 and 3, the limit as n approaches infinity of aₙ does not exist.
