Answer:

  1. B. the direct method
  2. B. 30°
  3. C. eqaully likes events

Step-by-step explanation:

1. In direct method we have to assume the hypothesis as we have assumed the hypothesis "Let OM be the perpendicular to chord AB" in this case hence the option is B

2. Let the angle of triangle be 2x , 3x , & 7x

By angle sum property:-

2x+3x+7x=180

∘

⇒12x=180

∘

⇒x=15

2x=2×15=30

∘

3x=3×15=75

∘

7x=7×15=105

∘

Smallest Angle=30

30 ∘

3. Equally Likely Events. Equally likely events are events that have the same theoretical probability (or likelihood) of occurring.
