Pls show complete solutions and explain them. Thank you! 4. Cancer is a disease caused by abnormal growth and proliferation of cellsin the body. A model is constructed to predict whether a cancer ismalignant (1) or benign (0) using uniformity in cell size (X1, score from 1to 10) and uniformity in cell shape (X2, score from 1 to 10). The biopsyresults of two hundred randomly selected patients from a certain hospitalwere used to construct the following model:π(y=1)In[((-²)] = −5.07 +0.60X₁ +0.79X₂[1¬n(y=1)]The confusion matrix for the constructed model is shown below:Outcome0 (benign)1 (malignant)The accuracy of the model isA. 7.0B. 62.0C. 91.8D. 93.0_%.Predicted Probability< 0.5> 0.51305956

4. Cancer is a disease caused by abnormal growth and proliferation of cells
in the body. A model is constructed to predict whether a cancer is
malignant (1) or benign (0) using uniformity in cell size (X1, score from 1
to 10) and uniformity in cell shape (X2, score from 1 to 10). The biopsy
results of two hundred randomly selected patients from a certain hospital
were used to construct the following model:
π(y=1)
In[((-²)] = −5.07 +0.60X₁ +0.79X₂
[1¬n(y=1)]
The confusion matrix for the constructed model is shown below:
Outcome
0 (benign)
1 (malignant)
The accuracy of the model is
A. 7.0
B. 62.0
C. 91.8
D. 93.0
_%.
Predicted Probability
