Answer:

The exact probability = 0.0431

Step-by-step explanation:

Given: A bag contain - Caramels= 12, mints= 12, bars of dark chocolates=  14

Marilyn picks three items from the bag without replacement.

Total number of items 12+12+14=36

Now, probability = favorable outcome / total no. of outcomes

Probability of picking a mint = \frac{12}{36}=\frac{1}{3}

After picking a mint there are :

caramels=10, mints=11, bars of chocolate=14

Total items in the bag=35

Probability of picking another mint =  \frac{11}{35}

now, caramels=10, mints=10, bars of chocolate=14

Total items in the bag=34

Probability of picking a bar of dark chocolate =  \frac{14}{34}=\frac{7}{17}

The exact probability of picking the items:

=\frac{1}{3}\times\frac{11}{35}\times\frac{7}{17}

=\frac{77}{1785}

=0.0431

Therefore, the exact probability = 0.0431

10+12+14 = 36

12/36 x 11/35 x 14/34 = 11/255

2 --> 10

3 --> 15

4 --> 20

5 --> 24

Step-by-step explanation:

Function means you can have one input for evry one output

so you have to change the 2 and 1 to diffrent numbers like 4 and 5

so now evey imput has their own out put

befor input one it had 5 and 24

What were the main important ideas in geometry that you studied in the first six weeks?
8090 [49]

Answer:

The preceding chapter explored implications of research on learning for general issues relevant to the design of effective learning environments. We now move to a more detailed exploration of teaching and learning in three disciplines: history, mathematics, and science. We chose these three areas in order to focus on the similarities and differences of disciplines that use different methods of inquiry and analysis. A major goal of our discussion is to explore the knowledge required to teach effectively in a diversity of disciplines.
