slide1

Probability

How likely it is that something will happen.

slide3

# of ways an event can occur

p =

total # of events

slide4

The event: rolling a 3 with one die

1 (# of ways the event occurs)

p =

6 ( total # of possible events)

slide5

Event: rolling a 5 with a pair of dice

# of ways the event can occur: 4

Probability of rolling 5 with a pair of dice

p =

p= p = .11

slide8

All events: 50 pieces of paper

10 green

20 red

15 yellow

5 blue

(papers are returned after each draw)

slide9

1) Prob. of two events both occurring

Event A and Event B

( Prob. A) (Prob. B)

slide12

Event: drawing a red and a yellow

prob of red and prob of yellow

p = .12

slide14

Probability does not have memory !

If the event is defined as two draws then this method applies.

If the event is limited to the second draw only, the probability is based on that event alone

slide15

2) The probability of either of two mutually exclusive events occurring is the sum of their probabilities.

Prob A or Prob B

(Prob A ) + (Prob B)

slide17

All events: 50 pieces of paper

10 green

20 red

15 yellow

5 blue

(papers are returned after each draw)

slide19

Mutually Exclusive:

When two events can not co-occur.

slide20

Events that are not mutually exclusive:

Using a standard deck of 52 playing cards,

Drawing a face card or a heart.

12 faces cards

13 hearts

3 cards that are face cards and hearts
