Answer :
The predicted probability of using the coupon by a customer who spends $3000 annually and does not have a Simmons credit card is 0.2369
Predicted probabilities are calibrated or scaled to mirror the discovered occurrence of class 1 activities by using a further regressor that uses the preliminary probabilities to expect the target variable which is the genuine chances. Theoretical probability makes use of math to predict the outcomes. just divide the favorable consequences by the possible consequences.
To calculate probability follow the following steps
In ( p / 1 - p ) = - 2.10 + 0.31[tex]x_{1}[/tex] + 1.20[tex]x_{2}[/tex]
[tex]x_{1}[/tex] = 3000 / 1000 = 3 ( in $1000 )
[tex]x_{2}[/tex] = 0 ( does not have )
In ( p / 1 - p ) = - 2.10 + 0.31(3) + 1.20(0)
In ( p / 1 - p ) = -1.17
p / 1 - p = [tex]e^{-1.17}[/tex]
p = 1 / 1 + [tex]e^{-1.17}[/tex]
p = 0.236854
Therefore predicted probability of using the coupon by customers is 0.2369
Probability is the department of arithmetic regarding numerical descriptions of the way possibly an event is to occur, or how likely it is that a proposition is true. The opportunity of an occasion is a range of between 0 and 1, in which, roughly talking, 0 indicates the impossibility of the occasion and 1 shows certainty.
