Solve the problem, rounding the answer as appropriate. Assume that "pure dominant" describes one who has two dominant genes for a given trait; "pure recessive" describes one who has two recessive genes for a given trait; and "hybrid" describes one who has one of each.Suppose a hybrid mates with a pure dominant. If they produce two offspring, what is the probability that neither is a hybrid?

Solve the system of equations using matrices (row operations). If the system has no solution, say that it is inconsistent.
A. inconsistent B. x = -4, y = 2; (-4, 2) C. x = 2, y = -4; (2, -4) D. x = -4, y = -2; (-4, -2)
