Dengan data tersebut, dapat di prediksi kondisi kemunculan litologi pada tabel diatas, dengan cara pembagian jumlah kemunculan pada setiap litologinya. Hasil yang didapat berupa Probability Matriks A = S0 pada metode downward, dan Probability Matriks A = S0 pada metode upward.

Probability Matriks A = S0 pada metode downward.

Penentuan nilai probabilitas dalam menentukan prediksi litologi yang akan muncul pada Downward dan Upward, dapat dilihat dali besar nilai asumsi probabilitas tersebut. Maka dipilih nilai probabilitas yang paling besar guna menentukan jenis litologi.
