Question

A bag contains 4 red balls,3 black balls and 5 yellow balls. A ball is drawn at random from the bag.Find the probability of getting a i) pink ball ii) black ball​

Answer 1

Answer:

0, 1/4

Step-by-step explanation:

Number of red balls = 4

Number of black balls = 3

Number of yellow balls =  5

i) Probability of getting a pink ball = 0 as there are 0 pink balls in the bag

ii) Probability of getting a black ball = 3/12 i.e 1/4

Answer 2

Answer:

Probability of getting i) pink ball = 0 and probability  of  getting  ii) black ball​ =1/4

Step-by-step explanation:

$\huge \text{Given}$

A bag contains 4 red balls,3 black balls and 5 yellow balls

$\huge \text{To Find The Probability of Getting\\ }$

i)  pink ball

ii) black ball​

Probability of an Event = Number of favourable outcomes          

                                                                       Total Events

ANSWER

Total Number of balls =  4 red balls+3 black balls+ 5 yellow balls = 12 balls

Probability of getting

i) pink ball = Number of pink balls     = 0/12 = 0

                                   12    

ii) black ball​ = Number of black balls          = 3/12 = 1/4                        

                                          12
