Question

a box contains 1 white and 3 identical black balls two balls are drawn at random in succession without replacement then what is the sample space​

Answer 1

total number of balls=4

it is given as without replacement

so let us take probability of getting no white balls

which will be equal to=3/4*2/3=6/12

so we will take denominator which is equal to 12

so sample space is 12
