A bag contains 5 white, 6 red and 4 green balls. One ball is drawn at random. WH
probability that the ball drawn is (i) green? (ii) white? (iii) non-red?​

Answer 1

Answer:

Step-by-step explanation:

-First, find the total number of balls in the bag.

Total number of balls in the bag = 5+6+4

                                                      = 15

i) probability of getting a green ball.

-Now write the total number of green balls as numerator and total number of balls in the denominator.

like this,

Total number of green balls = 4

Probability of getting a green ball = 4/15

-See if you can simplify the fraction into it's simplest form.

4/15 can't be cancelled further . So,

the rational form can be written as 4:15.

ratio = 4:15

∴The probability of getting a green ball = 4:15

- Do the rest in the same manner.

ii)White ball

Total number of white balls =5

Probability of getting a white ball = 5/15

-This fraction can be simplyfied into

5/15 = 1/3

ratio= 1:3

∴Probability of getting a white ball =1:3

iii)Non- red ball

- Here, we have to add both the green and white balls, because they are the non- red balls.

Total number of non-red balls =5+4

                                                  =9

∴Probability of getting a non-red ball =9/15

- Don't forget to simplify!

  9/15= 3/5

  ratio = 3:5

∴Probability of getting a non-red ball =3:5
