Probability

There's 4 coins in a cup- 0.25, 0.10, 0.05, 0.01
You draw 1 coin then put it back, then draw another coin. If those 2 coins add up to an even sum you win. If they add up to and odd sum you lose.
Do you want to play? Explain the odds, are they in your favor or not.

Organize Outcomes
Create a Table or a Chart




P (even sum)=10/16 or 5/8 or 62.5%
P (odd sum)=6/16 or 3/8 or 37.5%


A coin is flipped and a six sided die is rolled.These 2 are called independent events.
Independent event- The outcome of one event has no effect on the outcome of another event.
Sample Space- All possible outcomes of an experiment.

A coin is flipped and a six sided die is rolled
a)Use a table to list all possible outcomes.
b)How many possible outcomes are there
c)Write the sample space for this combination of events.



Possible outcomes:12
Sample space: (H1) (H2) (H3) (H4) (H5) (H6)
(T1) (T2) (T3) (T4) (T5) (T6)
Find P (heads and even)
3/12=1/4 or 25% or 1:4

  • Homework
    A toonie is flipped and a 4 sided die is rolled. Using a chart find the P(tails and odd#)
