प्रश्न
A box contains loo red cards, 200 yellow cards and 50 blue cards. If a card is drawn at random from the box, then find the probability that it will be a blue card
उत्तर
Total no. of possible outcomes = 100 + 200 + 50 = 350 {100 red, 200 yellow & 50 blue}
E ⟶ event of getting blue card.
No. of favourable outcomes = 50 {50 blue cards}
P(E) = `"No.of favorable outcomes"/"Total no.of possible outcomes"`
P(E) = 50/350 =1/7
