Answer:
5/6
Step-by-step explanation:
There are six sides on a die, and they are asking the probability of not rolling a 4. So it would be 5 out of 6
Have a good day :)
Answer:
a(n) = 

Step-by-step explanation:
The given expression is in the form of the explicit formula of a geometric sequence.
f(n) = 
Where 'a' = First term of the sequence
r = common ratio
Recursive formula of a geometric sequence is,
a(n) = 
a(n) = 
Where, 
So the recursive formula will be a(n) =
