1
00:00:02,035 --> 00:00:03,470
On the Guided Practice tab,

2
00:00:03,470 --> 00:00:05,806
you are able to set up two conditions of playing cards

3
00:00:05,806 --> 00:00:06,807
and see the probability

4
00:00:06,807 --> 00:00:09,710
of randomly drawing a card that meets those conditions.

5
00:00:09,710 --> 00:00:11,178
The carousel on the left represents

6
00:00:11,178 --> 00:00:13,647
the color of the card.

7
00:00:13,647 --> 00:00:17,184
The carousel in the middle represents the card’s suit.

8
00:00:17,184 --> 00:00:21,221
The carousel on the right represents the card’s rank.

9
00:00:21,221 --> 00:00:24,124
Drag a card from any of the carousels into box A

10
00:00:24,124 --> 00:00:27,427
to set the first condition.

11
00:00:27,427 --> 00:00:30,597
Drag another card into box B to set the second condition

12
00:00:30,597 --> 00:00:31,832
and display the probability

13
00:00:31,832 --> 00:00:35,335
of selecting a card that meets these conditions.

14
00:00:35,335 --> 00:00:37,838
The “and” conjunction is selected by default,

15
00:00:37,838 --> 00:00:40,474
but you can click on another conjunction from the list

16
00:00:40,474 --> 00:00:41,775
to display the probability of

17
00:00:41,775 --> 00:00:44,478
drawing a card that meets condition A or condition B,

18
00:00:44,478 --> 00:00:48,582
or a card that meets condition A but not condition B.

19
00:00:48,582 --> 00:00:50,584
Notice how the different conjunctions

20
00:00:50,584 --> 00:00:53,186
change the probability equation.

21
00:00:53,186 --> 00:00:54,521
You can change the conditions

22
00:00:54,521 --> 00:00:58,258
by dragging another card into the boxes.

23
00:00:58,258 --> 00:01:00,761
You can click on the Sapling Learning Deck at any time

24
00:01:00,761 --> 00:01:05,065
to see which cards meet the given conditions.

25
00:01:05,065 --> 00:01:07,801
Cards that are grey do not meet the given conditions,

26
00:01:07,801 --> 00:01:10,737
and cards that are white do meet the conditions.

27
00:01:10,737 --> 00:01:14,541
Click on the Deck again to close it.

28
00:01:14,541 --> 00:01:16,576
On the Workspace tab, you are able to set up

29
00:01:16,576 --> 00:01:18,111
two conditions of playing cards

30
00:01:18,111 --> 00:01:19,613
and calculate the probability of

31
00:01:19,613 --> 00:01:24,384
randomly drawing a card that meets those conditions.

32
00:01:24,384 --> 00:01:29,156
Click on each box in the equation to open the keypad.

33
00:01:29,156 --> 00:01:31,391
Use the keypad to enter the number of cards

34
00:01:31,391 --> 00:01:35,195
that meet each condition or the intersection.

35
00:01:35,195 --> 00:01:37,230
If you would like to look at a full deck of cards

36
00:01:37,230 --> 00:01:38,565
to help determine the values,

37
00:01:38,565 --> 00:01:41,735
you can click on the Sapling Learning Deck.

38
00:01:41,735 --> 00:01:44,338
Notice that all of the cards in the deck are white.

39
00:01:44,338 --> 00:01:45,706
The cards will not be grayed out

40
00:01:45,706 --> 00:01:50,811
until you have determined the correct probability.

41
00:01:50,811 --> 00:01:52,980
After you have entered values into all of the boxes,

42
00:01:52,980 --> 00:01:55,148
click “Check” to check your answer.

43
00:01:55,148 --> 00:01:57,317
If any of the values you entered are incorrect,

44
00:01:57,317 --> 00:01:58,618
an error message will appear

45
00:01:58,618 --> 00:02:01,288
and you can click on the box that is incorrect to try again.

46
00:02:03,290 --> 00:02:05,359
When you have correctly determined each value,

47
00:02:05,359 --> 00:02:07,494
the total probability of selecting a card

48
00:02:07,494 --> 00:02:11,098
that meets the given conditions will be displayed.

49
00:02:11,098 --> 00:02:13,100
You can also click on the Sapling Learning Deck

50
00:02:13,100 --> 00:02:15,402
to see the cards that meet the given conditions.

51
00:02:17,471 --> 00:02:19,740
Click “Try another” to try another example.
