For an experiment in science class, students roll a number cube with faces numbered 1 to 8, then draw a card from deck of 3 cards - the ace of hearts, queen of spades, and eight of clubs, and then finally flip a coin. How many possible outcomes are there for this experiment ? PLZZ HELP !!!!

How many possible outcomes are there when you roll the cube of 8 faces?

Use the counting principle.

@welshfella im not sure

there are 8 numbers right? so if you roll the dice any one of 1 to 8 will be obtaines So that is how many outcomes?
anonymous

8 @welshfella
welshfella
  • welshfella
right so for every 1 of the eight numbers you will get any 1 of the 3 cards - that's a possible number of outcomes of 8 * 3 = 24. (this is the counting principle)

Flipping a coin has 2 outcomes Heads and tails so possible outcomes for the whole experiment = 24 * what?

Um 24*8 ??
welshfella
  • welshfella
no - we are dealing with the coin now - 2 outcomes
welshfella
  • welshfella
for everyone of the 24 outcomes we can get a head or a tail

24*2
welshfella
  • welshfella
so it 24 * ?
welshfella
  • welshfella
right
anonymous
  • anonymous
Which is 48
welshfella
  • welshfella
its 8*3*2 = 48
welshfella
  • welshfella
yea

The counting principle is find how many ways each thing can happen and multiply them all together.
mathstudent55
  • mathstudent55
cube: 8 outcomes cards: 3 outcomes coin: 2 outcomes total outcomes: 8 * 3 * 2 = 48 You are correct.
