Bag A=5White, 2 Black balls Bag B=2 White, 3 Black balls. Probability of selecting a bag = 1/2 Now, the Probability of picking a black ball = from bag A or from bag B = ²C ₁ /³C ₁ + ³C ₁ /³C ₁ =2/5+3/5 = 1 So, required probability = (1/2) *1 = 1/2
sin2 9 ° + sin2 10 ° + sin2 11 ° + sin2 12 ° + ……… + sin2 81 ° = ?
...If 4cos2x - 3 = 0, and (0° > x > 90°), then find the value of 'x'.
If tan θ = (2/√5), then determine the value of cos2 θ
If √3cosec 2x = 2, then the value of x:
If x = (sin 30 ° + cos 30 ° )/sec 60 ° , then find the value of 4x.
If sin3A = cos(5A-30°), then what is the value of A? Given that 3A is an acute angle.
If sin x + cos x = √2 sin x, then the value of sin x - cos x is:
Simplify the given equation:
