Hey there!
To find how many rolls were sold in the morning, you must multiply 54, the total amount of rolls, by 1/6, the amount of the whole sold in the morning. This would be represented by this expression:
54*1/6
Now, simplify the expression to find how many rolls were collected in the morning:
54*1/6=54/6
54/6=9
Therefore, 9 rolls were sold in the morning.
Hope this helps and have a marvelous day! :)
The third tree diagram is correct.
The probabilities for the first draw are 3/7 for green and 4/7 for red.
If you draw a green pear first, then your probabilities for the second pear would be 2/6 for green and 4/6 for red (since it is done without replacement, the number of pears to choose from changes).
If you draw a red pear first, then your probabilities for the second pear would be 3/6 for green and 3/6 for red.
