how to connect interpolation and probability

starting from 3 distance values and 3 speed values I managed to create this grid by interpolating all the values (the colored points) and thus obtaining all the other speeds: new_speed = interp1 (distance, speed, new_distance, 'linear').
Now on each of these points I should add another information, that of probability. Also in this case I have only 3 information on probabilities, each relating to a speed and a distance. can anyone help me?
the code is:
prob_a=[10.48 23.31 23.46 18.20 11.50 6.99 2.77 1.02 0.32 0.05 10.48]; %55km-7m/s
prob_b=[6.76 14.58 15.19 12.47 8.20 5.12 2 0.75 0.24 0.03 6.76]; %500km-30m/s
prob_c=[0.36 0.54 0.36 0.15 0.06 0.01 0 0 0 0 0.36]; %667km-70m/s
z1 = calcola_dist
x = [0 55 500 667]; %distance
v = [0 7 30 70]; %velocity
xq = z1; %new distance
vq2 = interp1(x,v,xq,'linear');
plot(lonlatgrd(:,1),lonlatgrd(:,2),'.');
hold on
scatter(lonlatgrd(:,1),lonlatgrd(:,2),20,vq2,'filled');
colormap hsv
colorbar

Some of your data, used in your code, are not provided here. Moreover, it is not quite clear "connect"? What you are trying to do is to see how much your interpolated data correlates with the probability data or something else?
