Write TRUE or FALSE for following cases:-?

CASE1


=======


Aquare isdivided into a 5 by 5 red andwhite checkerboard


pattern,with the corner squarescoloured red.


This means 50% of theentirequare is coloured red.








CASE 2


========





There ar 6 persons at a party.Each one shakes hands [only] once with everyother person.





Then there will be 15 handshakes altogether.Write TRUE or FALSE for following cases:-?
CASE -1 FALSE


=========





CASE-2 TRUE


========Write TRUE or FALSE for following cases:-?
Amazes me that you pick the person who just gave you the answers and no work. Apparently, you just wanted the answers. lol

FALSE: Because the square would have 25 smaller squares and 25 is an odd number, so red would have 13, the other (black) would have 12.

TRUE: 5 + 4 + 3 + 2 + 1 = 15


Formula is HS = (n-1) + (n-2) + (n-3) + (n-4) + (n-5)


HS = Handshakes


n = 6 (Total People)
case 2 is true because of the following reasons


Let the 6 persons are A,B,C,D,E,F


A gives shake hands to B,C,D,E,F = 5


B gives shake hands to C,D,E,F = 4


C gives shake hands to D,E,F = 3


D gives shake hands to E,F = 2


E gives shake hands to F = 1


So total shake hands = 15


hope this is clear
Case one is false because the amount of spaces coloured red will be more than the amount not coloured, so therefore it means the amount of spaces coloured red is more than fifty percent.


Case two is true.


ab, ac, ad, ae, af, bc, bd, be, bf,cd, ce, cf,de, df, ef
The first one is False, because the bottom will be the corners red and the top of the half will have the corners red.





The second one is True here's a picture.

well that may not have worked out but im sure its true.


These are my educated guesses.
true


false

CASE 1 is false because there can not be 50% of 25 squares.


CASE 2 is true because 6C2 = 15 (that's the formula for finding the number of handshakes)
CASE 1: True


CASE 2 : False only 10 not 15
a 5x5 checkerboard will have 25 squares. 50 percent is not possible - false.
case 1 false : 13 squares red, 12 squares white





case 2 : true I think
case 1: false. 13 out of 25 is more than 50%


case 2: true. 6C2= 15



true


false
