a die is tossed four times. A success is getting 1 or 2 on a toss find the mean and variance of the number of success |
|
Answer» Let x be the random variable denoting the number of times an odd number (the number of successes) when a DIE is tossed twice. Then x takes the values 0,1,2 Let P(X=0) be probability of getting no odd number (both times showing even). ∴P(X=0)= 6 3 × 6 3 = 4 1 Let P(X=1) be probability of getting odd number once. ∴P(X=1)=2C 1 6 3 × 6 3 = 6 6 × 6 3 = 2 1 Let P(X=2) be probability of getting odd number twice. ∴P(X=2)= 6 3 × 6 3 = 4 1 Thus the probability distribution of X is GIVEN by X=x x=0 x=1 x=2 P(X=x) 4 1 2 1 4 1 We know that mean E(X)=∑x i P i =0× 4 1 +1× 2 1 +2× 4 1 ∴E(X)=0+ 2 1 + 2 1 =1 Thus mean E(X)=1. We know that var(X)=E(X 2 )−[E(X)] 2 E(X 2 )=∑x i 2 P i =0× 4 1 +1 2 × 2 1 +2 2 × 4 1 ∴E(X 2 )=0+ 2 1 +4× 4 1 = 2 3 Thus var(X)= 2 3 −[1] 2 = 2 3 −1= 2 1 HENCE mean is 1 and variance is 2 1 |

1) Factorise the given polynomial :(x2 – x)2 – 8 (x2 – x) + 12. |
|
Answer» Answer: The polynomial is (x2−x)2 −8(x 2 −x)+12 y=(x2−x) Step-by-step explanation: Then the polynomial becomes, y 2 −8y+12 =y 2 −6y−2y+12 =y(y−6)−2(y−6) =(y−2)(y−6) =(x 2 −x−2)(x 2 −x−6) Now both factors can be further FACTORIZED, (x 2−2x+x−2)(x 2−3x+2x−6) ={x(x−2)+1(x−2)}{x(x−3)+2(x−3)} =(x+1)(x−2)(x+2)(x−3) |
