Probability Continued

Today in class we talked about Organizing Outcomes.

For eg. If you were playing a game and you were going to pick a number you will organize how many ways you can make that number with different cards. Like there were 3 cards left and there was 2 people. You will do it like (3,1) (3,2) (2,1) (2,2) (1,2) (1,2). You could also do a chart. We also talked about Independent Events and Sample Space.

Independent events- the outcome of one event has no effect on the outcome of another event.

Sample space- all possible outcomes of an experiment.

we had a question which was A coin was flipped a six-sided die is rolled.

a)Use a table to list all possible ways.

b)How many possible outcomes are there

c)Write the sample space for this combination of events.



A there is (1,heads) (1,tails) (2,heads) (2,tails) (3,heads) (3,tails) (4,heads) (4,tails) (5,heads) (5,tails) (6,heads) and (6,tails)

B There are 12 possible outcomes (aka) also known as sample space.

C The sample space is the numbers and tails of A.

We also talked about Second way and Tree diagram.

Second way- to organize outcomes.

Tree diagram- a diagram used to organize outcomes contains a branch for each possible outcomes of an event.

Her are some pictures of Tree Diagram
