Answer:
Step-by-step explanation:
The probability of an event to occur is given by a fraction:
Your favourable cases are given by the number of red face cards, that is the Jacks, the Queens and the Kings of Diamonds and Hearts, this number is 6.
The total number of cases is given by the total number of the cards, that is 52.
So the probability of drawing a red face card is:
That is ≃ 0,115... = 11,5%

The estimated regression equation:
ŷ = 2.73953X + 27.91395
Where ;
X = independent variable
ŷ = predicted or dependent variable
27.91395 = intercept
C.) To obtain the variation in sample values of height estimated by the model, we obtain the Coefficient of correlation:
Using the online pearson correlation Coefficient calculator :
The correlation Coefficient is 0.9696.
which means that the regression model estimated in part (b) explains approximately (0.9696 * 100) = 96.96% = 97% of the variation in the height in the sample.
