# 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 - Mathematics

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

#### Solution

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
