Question

A box caintains 100 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

Answer 1

p=probability
B=blue           Y=yellow             R=red

p(B) =50/350
        = 1/7

p(Y) =200/350
        = 4/7

p(R) =100/350
        = 2/7

Answer 2

Answer:

Probablity of:

Red card:  2/7

Yellow card: 4/7

Blue cards:  1/7

Step-by-step explanation:

Total Number of cards: 100+200+50= 350

Red cards= 100/350

If we further simplify it, we end up with 2/7

Yellow cards: 200/350

If we further simplify it, we end up with 4/7

Blue cards: 50/350

If we further simplify it, we end up with 1/7
