Step-by-step explanation:
With each draw, the probability of selecting a green marble is 2/3 and the probability of selecting a yellow marble is 1/3.
To pick two of the the same color, they can either pick green twice or yellow twice.
P = (2/3)(2/3) + (1/3)(1/3)
P = 5/9
To pick two different colors, they can either pick green first then yellow, or yellow first then green.
P = (2/3)(1/3) + (1/3)(2/3)
P = 4/9
Expected value for Derek is:
D = (5/9)(-1) + (4/9)(1)
D = -1/9
The expected value for Mia is:
M = (5/9)(1) + (4/9)(-1)
M = 1/9
Answer:
Step-by-step explanation:
Well is she wanted to make $80 “b” she would have to garden for 16 hours to make a maximum of $80
“C” if she wanted to make it out of babysitting she would have to work the same for 8 hours if she babysit
Workout : b part = 10+10+10+10+10+10+10+10 Key:10=2
:c part = 20+20+20+20. Key:20=2
Sorry I didn’t do a but just add all the things above and u get your answer
2 and the 4 needs to add subtract too much
The data type of the recorded data is a. nominal.
In statistics, there are different types of data which includes nominal, ordinal, ratio, and interval data.
For nominal data, they are mainly used for identification and classification of variables. or simply put, they are used for labelling variables and has no numerical value attached to them.
In the example given above, each recorded choice of each person in the group would be recorded as nominal data for the sake of classification. The photographs can be labelled using letters or assigned numbers. However, these numbers are merely for identification purpose.
Therefore, the data type recorded is a. nominal.
