If a discrete random variable X follows uniform distribution and assumes only the values 8, 9, 11, 15, 18, 20, the value of P(|X-14| < 5) will be:
The correct answer is D
I. 7x² + 27x + 18 = 0
II. 19y² - 27y + 8 = 0
Quantity I: A vessel contains a mixture of milk and water in the ratio of 7 : 5. If 9 litre of mixture is sold and replaced by same amount of water the...
I. p² - 10p +21 = 0
II. q² + q -12 = 0
I. 2x² - 15x + 27 = 0
II. 2y² - 13y + 20 = 0
I. x² + 11x + 24 = 0
II. y² + 17y + 72 = 0
I. x² + 3x – 154 = 0
II. y² + 5y – 126 = 0
I. 165x² + 97x + 10 = 0
II. 117y² - 163y + 56 = 0
I. 20x² - 93x + 108 = 0
II.72y² - 47y - 144 = 0
I. 6x² - 49x + 99 = 0
II. 5y² + 17y + 14 = 0
I. 6x2 – 7x - 20 = 0
II. 3y2 - y - 14 = 0
