Let T (x, y) mean that student x likes cuisine y, where the domain for x consists of all students at your school and the domain for y consists of all cuisines. Express each of these statements by a simple English sentence. a) ∃x∃z∀y(T (x, y) ↔ T (z,y)) b) ∀x∀z∃y(T (x, y) ↔ T (z,y)) My doubt is what is the difference between both of them?

Combinatorics Question on Bit Strings
How many bit strings of length 8 contain either three consecutive 0's or four consecutive 1's ? MY APPROACH :- Initially, for 3 consecutive 0's: 000_ _ _ _ _ =>2^5 = 32 WAYS 1000_ _ _ _ =>2^4 = 16 WAYS _1000_ _ _ =>2^4 = 16 ... ;2*3! = 12 WAYS so, total ways = 112 + 48 - 12 = 148 ways But answer is given as 147 ways. Where am I wrong?
