 I welcome to the session where is discussed the following question. The question says show that in Boolean and Trefla, A or A complement and B is equal to A or B. Now we begin with the solution. Now let's first consider A or A, A complement and B. Now by using the distributive law we can write this as A or A complement and A or B. We know that A or A complement is equal to 1, right? So this is equal to 1 and A or B. We know that 1 and A is equal to A, so this is equal to A or B, complement and B is equal to A or B. This completes the session. Bye and take care.
