Q.1 Ch - Probability
Q.2 Ch - Triangles
Class 10th​

Answer 1

Answer:

Question 23. Correct option is (D) 10/7

Bcs, probability greater than 1 is not possible, and 10/7 = 1.4

That's why option (d) can't be the probability.

Hence, answer is..

D) 10/7

Question 24.

Correct ans is option (C) ∠B = ∠D

Bcs, AB/DE = BC/FD

=> AB/BC = DE/FD

By this ratio we can conclude that, ∠B and ∠D are the corresponding common angles, between AB, BC and DE, EF

So, if ∠B = ∠D, then by SAS Similarity, triangle ABC and triangle DEF are similar.

Hence, answer is..

C) ∠B = ∠D
