Which geometric series converges 1/81+1/27+1/9+1/3+, 1+1/2+1/4+1/8?

- is a converging geometric series.

Explanation:-

The geometric series is given by  

If |r| < 1 then the geometric series converges to.

If |r| ≥1 then the geometric series diverges.

1)

here

⇒The geometric series diverges.

2)

here

⇒The geometric series converges.

because they could drop even lower..

3-4

step-by-step explanation:

the answer is 3-4 because both 45 and 60 has a multiple of 15.

45/3=15

60/4=15

therefore the odds against selecting a red is 4-3
