The directrices are x =
The equation of tangents to the hyperbola 3x2 - 2y2 = 6, which is perpendicular to the line x - 3y = 3, are
If the mean and variance of a binomial distribution are 4 and 2, respectively. Then, the probability of atleast 7 successes is
C.
Given, mean = 4 and variance = 2
np = 4 and npq = 2
Then, p = 1 - q = 1 - =
Mean = np = 4
The required probability of atleast 7 successes is
