Given below is the distribution of a random variable X

If `alpha = P ( X lt 3)` and `beta = P (X gt 2 )` , then `alpha , beta = `

The probability of a random variable X is given below Determine P (X le 2) and P (X gt 2)

The probability distribution of a random variable X is given as under: Find k , and P (X lt 6) .

The probability of a random variable X is given below Find P (X le 2 ) + P (X gt 2)

If alpha , beta are the roots of x^2 +x+1=0 then alpha beta + beta alpha =

If alpha , beta ,1 are roots of x^3 -2x^2 -5x +6=0 ( alpha gt 1) then 3 alpha + beta=

If alpha , beta are the roots of x^2-p(x+1)+c=0 then (1+alpha )( 1+ beta )=

If alpha, beta and 1 are the roots of x^3-2x^2-5x+6=0 , then find alpha and beta

A random variable X follows binomial distribution with mean alpha and variance beta . Then,

If alpha, beta be the roots of 4x^2-17x+lambda=0, lambda in R such that 1 lt alpha lt 2 and 2 lt beta lt 3 then the number of integral values of lambda is

If alpha, beta are the roots of the quadratic equation x^2 + bx - c = 0 , the equation whose roots are b and c , is a. x^(2)+alpha x- beta=0 b. x^(2)-[(alpha +beta)+alpha beta]x-alpha beta( alpha+beta)=0 c. x^(2)+[(alpha + beta)+alpha beta]x+alpha beta(alpha + beta)=0 d. x^(2)+[(alpha +beta)+alpha beta)]x -alpha beta(alpha +beta)=0
