what is the probability of drawn an ace or a space or both from a dew of cards.

• There are 13 spades in a standard deck of cards.
  
  There are four aces in a standard deck of cards.
  
  One of the aces is a spade.
  
  So, 13 + 4 - 1 = 16 spades or aces to choose from.
  
  Since we have a total of 52 cards, the probability of selecting an ace or a spade is 16 / 52..

• The probability of an ace or a spade.
  
  The probability of an ace is 4/52.
  
  The probability of a spade is 13/52
  
  But, we have to subtract off the ace of spades else we double count it.
  
  4/52+13/52-1/52

• for ace =4/52
  for spade=13/52
  ace or a space or both from a dew of cards.=4/52-13/52-1/52

• Select ace 4C1=4
  Select spade 13C1=13
  Total 52C1=52
  So, ans is ((4+13) - 1) /52
  Subtract 1 bcoz ace card in spade is already choose therefore answer is 16/52 ie 4/13

• probability of choosing ace=4/52
  probability of choosing spade=13/52
  probability of choosing both(ace in spade)=1/52
  probability of choosing either of the three=4/52+13/52+1/52=18/52
  is this the right answer someone help me to clear it?

• Let's assume there are 100 students in a school, cuz taking 100 value is much easier than other
  so, here we go out of 100 students 60% are girls =60.
  In that 60 girls 35% are poor = 35/100X60=>21 Students poor
  so No of events = 21
  upon total strength = 100
  21c1/100=21/100
