In an experiment, a deck of cards containing different colored cards is shuffled. Four cards are randomly selected and the numbe

r of green cards selected is recorded. One hundred twenty trials of the experiment are run.
The table shows the frequency of 0, 1, 2, 3, or 4 green cards occurring in the trials.

Number of green cards 0 1 2 3 4
Frequency 12 18 54 24 12

We can calculate probability distributions according to the number of occurrence of green cards. Probabilities are:

P(x=0)= \frac{12}{120}= \frac{1}{10}=0.1
P(x=1)= \frac{18}{120} = \frac{3}{20}=0.15  
P(x=2)= \frac{54}{120}= \frac{9}{20}=0.45
P(x=3)= \frac{24}{120}= \frac{1}{5}=0.2
P(x=4)= \frac{12}{120}= \frac{1}{10}=0.1

When we plot these results, we get this following graph

Points (0,6) and (-4,y) lie on the line with a slope of 5
Anna [14]

For this case we have that by definition, the slope of the line is given by:

m = \frac {y_ {2} -y_ {1}} {x_ {2} -x_ {1}}

According to the statement we have:

(x_ {1}, y_ {1}) :( 0,6)\\(x_ {2}, y_ {2}): (- 4, y_{2})\\m = 5

Substituting the values:

5 = \frac {y_ {2} -6} {- 4-0}\\5 = \frac {y_ {2} -6} {- 4}\\5 * -4 = y_ {2} -6\\-20 = y_ {2} -6\\-20 + 6 = y_ {2}\\y_ {2} = - 14

Thus, the value of y_ {2} = - 14

Answer:

y_ {2} = - 14
