Answer:
36
Step-by-step explanation:
This question can be solved using fundamental counting principle which means to say that if there are "m" ways of doing one thing and there are "n" ways of doing other thing then there are total "m*n" ways of doing other things.
For example: if there are 4 type of pens and 3 type of notebook then there are "4*3" ways to write on notebook using the pens.
_____________________________________________________
Using the above mentioned principle we have
six sided cube with number 1 to 6 written on it hence in first roll there are six possible outcome(1 or 2 or 3 or 4 or 5 or 6) similarly there are 6 possible outcome in other roll as well.
If the combination of outcome is to be deduced then there are 6*6 ways of outcome based on fundamental counting principle.
Hence there are 6*6 = 36 ways of possible outcomes.

Answer:
0.0821
Step-by-step explanation:
If the arrival rate is 50 customers per hour (60 minutes), then the expected number of customers in 3 minutes is:
Assuming a Poisson distribution with 2.5 customers per 3 minutes, the probability that zero customers arrive for 3 minutes is:
The probability that the bank stays empty for three minutes is 0.0821.
