a bag contains 2 samsung mobiles, 6 redmi mobiles and 8 lenovo mobiles . 3 mobiles are drawn one by one with replacement, what is the probability that all are lenovo mobiles

Answer 1

Hi.....
nobody try to solve this question , now it my turn ,

total mobile in bag=2+6+8=16

probability of Lenovo mobile=8/16=1/2

so it is replace everytime so probability is not change, i.e it always 1/2

so for 3mobiles withdraw then

1/2*1/2*1/2=1/8

1/8 is the probability of all 3mobiles are lenovo

so u got ur answer

smile ,thanks for asking
