Question

a box contains20 cards numbered from1-20.a card is drawn from the box at random. find the probability that the number in the drawn card is (1) even,(2) multiple of three​

Answer 1

Answer:

Answer 2

Answer:-

Total number of cards = 20

(1) Card is even

Favourable outcomes = 10

So, Probability = 10/20 = 1/2

(2) Multiple of three

Favourable outcomes = 6

Probability = 6/20 = 3/10

-------------------

• Probability = Favourable outcomes/Total number of outcomes.

• P(E) + P(not E) = 1

• Probability can only be less than equal to 1 and more than equal to 0.

• If Probability is 1, then it is sure event.

• If Probability is 0, then it is impossible event.
