How do I know what is the probability that this file belong to this class .wav

On the TransferLearningUsingGoogLeNetExample for images, the code was able to predict the class of the image with probability % that this file is belong to this class. I am trying to do that with "signal procssing example Classify Sound Using Deep Learning" example. Once I trained my model and test it with one file, I want the classifer to show this file belong to this class with %100, %70, %40 etc.

idx = randperm(numel(imdsValidation.Files),4);
figure
for i = 1:4
    subplot(2,2,i)
    I = readimage(imdsValidation,idx(i));
    imshow(I)
    label = YPred(idx(i));
    title(string(label) + ", " + num2str(100*max(probs(idx(i),:)),3) + "%");
end

num2str(100*max(probs(idx(i),:)),3) + "%");

The last line of this code, they shows what probability of tested file to be in this class. The testing code on the "signal procssing example Classify Sound Using Deep Learning" example

wNoiseTest = 2*rand([N,1]) - 1;
classify(net,extract(aFE,wNoiseTest)')

Yessss.. I figured it out :)

prob = predict(net,extract(aFE,wNoiseTest)');
