You can put this solution on YOUR website! Can't help you with the first two because there is not enough info and besides you can only submit one question at a time limit of 4 submissions daily and no similar questions
so draw a Venn diagram of two circles such that they overlap.
info given 130 total players 48 played poker 84 played blackjack and 16 both
first fill in the overlap with 16
then subtract 16 from 42 and put 26 in the poker only
subtract 16 from 84 and put 68 in the bj only part
that answers numbers i and ii
add 16,26 and 68=110 one or both
130-110 =20 neither
