Hello,

I am looking at the solution for this problem and some steps were missed. I do not get how pb=0.4 was obtained in 1b. I used substitution but that didn't work. I used matrix reduction, that worked but for another problem of the same nature, it didn't work so why is pb obtained as this solution is missing steps.
Thanks!
