Question

A bag contains 2 white and 3 red balls two balls are selected at random find the probability of getting one white and one red ball

Answer 1

hi

NUMBER OF TOTAL OUTCOMES= 2+3=5

first :-

p(of getting 1white ball) = no. of respective ball / total no.

i.e --- 2/5

second:-

p(of getting a red ball) = no. of black balls /total no.

i.e ---- 3/5

so the probability of getting 1 white and 1 red ball is 2/5 &3/5 respectively

hope it helped
