A box contain 2 white and 3 blue identical balls. If two balls are picked at random, one after the other, without replacement, what is the probability of picking two balls of different colours?
In ∆PQR. ∠PQR is a right angle. |QR| = 2cm and ∠PRQ = 60o. Find |PR|
In the diagram, PQ||SR. Find the value of Z
In \(sin(X+30)^o=cos40^o\),find X
Find the value of X if \(cos x = \frac{5}{8}\) for \(0^o\le X\le 180^o\)
