Question

Q19. The measures of three interior angles of a triangle are 40°, 60°, 80°.The measures of three exterior

angles are 140°, 120°, 100° respectively. One of the six angles is chosen at random. What is the

probability that the angle chosen is (i) interior angle (ii) right angle (iii) an obtuse a​

Answer 1

Answer:

The probability that the angle chosen is interior angle = 3/6 = 1/2

The probability that the angle chosen is an obtuse angle = 3/6 = 1/2
