Please follow the comment Math notation question: does " ; " means '"and " ? also, does ", " means "and" ?
Example1: B = {(x, y); x ∈ [1, 2], y ∈ [1, 2], x < y}. does " , " means " and " here? could i replace "," to " ; " ?
Example2:S = {(x, y, i) : x = H, T; y = H, T; i = 1, 3, 5} Does " ; " means " and " here?
Comma (,) usually represents OR in math notation but not AND. Semi colon (;) represents sometimes Where and sometimes AND in math notation. However AND and WHERE have same meaning.
" ; " means '"and "
", " does not mean "and"
Example1:
B = {(x, y); x ∈ [1, 2], y ∈ [1, 2], x < y}.
Here " , " does not mean " and "
You could not replace "," to " ; "
Example 2:
S = {(x, y, i) : x = H, T; y = H, T; i = 1, 3, 5}.
Here " ; " means " and "

does (x,y)^T = vector <x,y> ???? i saw this notation at the book but i have no idea please follow the comment
Please explain and follow the comment: First of all, i don't understand what it means the bridge hand is void in at least one suit because I don't play bridge. Does that mean in 13 cards, it only has 3 suits? 54. Compute the probability that a bridge hand is void in at least one suit. Note that the answer is not 4 39 113 52 13 (Why not?) Hint: Use Proposition 4.4. y
