n = -2
Answer:
38
Step-by-step explanation:
f(x)=6x+2
6x6 (6 sqaured)
f(36)=36x+2
Now we add 36+2
38
We are simplifying this so they are easier to add in your head.
87+33 is easier math to do in your head
so our new estimated number would be 120
Answer: 0.973

The probability mass function of geometric distribution is
, p= probability of success on a trial.
As per given, we have
p=0.7
The probability that we'll have at most 3 orders 

hence, the required probability = 0.973
