उत्तर
A box contains 5 red, 4 green and 8 white marbles and a marble is drawn at random.
To find: Probability of getting a marble red
Total number of marbles: `5+4+8=17`
The total number of red marbles is 5.
We know that probability = `"Number of favourable event"/"Total number of events"`
Hence, the probability of getting red marble = `5/17`
