If the probability of drawing athrice that of drawing a white ball, find the number of black balls in the bag1 5cm and a semicircle of radius 45 cm |
|
Answer» No. of white balls = 15Let, the no. of black balls be 'x'Then, total no. of balls = 15 + xNow, P(drawing a white ball) = 15/(15 + x)And, P(drawing a black ball) = x/(15 + x)But A/Q, x/(15 + x) = 3*15/(15 + x) => x = 3*15 => x = 45Therefore, there are 45 black balls in the bag |

|
Answer» Out of two friends, one girl say, Maheshs bday can be any day of the year. Now, sarath's bday can also be on any day out of 365 days in the Year. We assume that these 365 outcomes are equally likely.(i) If Mahesh's bday is different from Sarath's, the no. Of favorable outcomes for her bday is 365-1= 364 So, P(Mahesh' bday is diffrent from Sarath's bday)=364/365 (ii) P(Mahesh and Sarath have the same bday)= 1-P(Both have diffrent bdays)=1-(364/365) [ using P(not event)=1-P(E)]=1/365 |

Answer» 8x + 3y = 11 ....................(I) ==> 3x - y = 2 ...................(II) In equation (II) it is easy to express y in terms of x. 3x - y = 2 3x -2 = y Substituting y = 3x - 2 in equation (I) 8x + 3y = 11 8x + 3(3x - 2) = 11 8x + 9x - 6 = 11 17x - 6 = 11 17x = 11+6 17x = 17 x = 17/17 x = 1 Now,substituting the value of x in the equation y = 3x - 2 y = 3x - 2 y = 3 x 1 - 2 y = 3 - 2 y = 1 So,x = 1 and y = 1 are the solution of the given equation..
