Let y1 and y2 denote the number of times that persons a and b toss the coin, respectively. if heads occurs with probability p and tails occurs with probability 1−p, it is reasonable to conclude that y1 and y2 are independent and that each has a geometric distribution with parameter p. consider y1−y2, the difference in the number of tosses required by the two individuals.

find v[y1y2].

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.

answer:   c ?

step-by-step explanation:

e^-kt = n/n0 = 0.79  

-kt = ln 0.79  

t = - ln 0.79/0.0001  

= 2357 years
