Question

12 cards, numbered 1 to 12, are placed in a box, mixed up throughly and then a card is drawn at random from the box. if it is known that the number on the drawn card is more than 3, find the probability that it is an even number

Answer 1

hello friend

there are 12 card then total outcome is 12
there are 6 even between 1 to 12
probability= posible events/total events
p(s)= 6/12
p(s)= 1/2




thanks dear

Answer 2

Total number of outcomes=12

possible outcomes=5

probability=no.of outcomes/total no. of outcomes

p(E)=5/12
