Answer: 1,679,616 different outcomes
(a little over 1.6 million)
To get this answer, you multiply eight copies of "6"
which can be written in shorthand as exponential notation
6^8 = 6*6*6*6 * 6*6*6*6 = 1,679,616
A smaller similar example is if you roll 2 dice making you have 6^2 = 6*6 = 36 different outcomes. All of the 36 outcomes can be represented in a table that has 6 rows and 6 columns.
Hello!
You first have to put the probability of him getting the bus and the train
for the first time he has a 2/3 chance of picking one
For the second time he has a 1/3 chance since he has to get the one he hasn't used yet
You multiply these together
2/3 * 1/3 = 2/9
The answer is 2/9
Hope this helps!
