Its, wrong bcoz...... probability = favourable outcomes / total number of outcomes if we throw a dice , total number of outcomes = 6 thus the probability of getting 1 = 1/6...... and nt getting 1 = 5/ 6......

If two triangles are similar then ratio of the perimeters of the triangles is equal to the ratio of their corresponding sides. Let the required side be 'x' Following this theorem, just plug the values 30/20 = 12/x 3/2 = 12/x x = 24/3 x = 8 So required value of the corresponding side is 8 cm
