There are two red cards in each set given in the drawing. What is the probability of picking 



 
 

aTotal number of cards = 5Total number of possible outcomes = 5Number of red cards = 2Number of favourable outcomes = 2Required probability = Number of favourable outcomesTotal number of possible outcomes = 25b.Total number of cards = 2Total number of possible outcomes = 2Number of red cards = 2Number of favourable outcomes = 2Required probability = Number of favourable outcomesTotal number of possible outcomes = 22 = 1c.Total number of cards = 6Total number of possible outcomes = 6Number of red cards = 2Number of favourable outcomes = 2Required probability = Number of favourable outcomesTotal number of possible outcomes = 26 = 13d.Total number of cards = 8Total number of possible outcomes = 8Number of red cards = 2Number of favourable outcomes = 2Required probability = Number of favourable outcomesTotal number of possible outcomes = 28 = 14

Similarly you can solve the other parts.
