Comparing (1) and (2), we get:
Also, given that
Using (3), we get, x + 2y = 3 . ...............(6)
Adding (5) and (6), we get
A pair of dice is thrown 4 times. If getting a doublet is considered a success, find the probability distribution of the number of successes.
Using integration find the area of the region bounded by the parabola y2 = 4x and the circle 4x2 + 4y2 = 9.
