- 10) none of these.
a pack of 52 cards contain 4 suits each with 13 cards.
so drawing 2 cards from a suit can be done in 13c2 ways. and there are 4 such suits, either of 4suits can be drawn. so total num of successes =4*13c2. and num of events occuring= 52c2(as we are drawing 2cards from 52).
so, total probability=(4*13c2)/52c2=12/51. - 12 years agoHelpfull: Yes(9) No(0)
