Answer:

a) $\frac{\sqrt{15} }{\sqrt{5}}\cdot \frac{\sqrt{5} }{\sqrt{5}}=\frac{\sqrt{75} }{5}=\frac{5\sqrt{3}}{5}=\sqrt{3}$

or simply

$\frac{\sqrt{15}}{\sqrt{5}}=\sqrt{\frac{15}{5}}=\sqrt{3}$

b) $\frac{\sqrt{3}\:}{\sqrt{6}} \cdot \frac{\sqrt{6}\:}{\sqrt{6}}=\frac{\sqrt{18} }{6}=\frac{3\sqrt{2} }{6}=\frac{\sqrt{2} }{2}$

$\frac{\sqrt{3}}{\sqrt{6}}=\sqrt{\frac{3}{6}}=\sqrt{\frac{1}{2}}$

$\sqrt{\frac{1}{2}}=\frac{\sqrt{2} }{2}$

9. The probability of a child being born with light-colored eyes to two particular parents is 0.25.

slavikrds [6]

If X is a random variable representing the number of children that end up having light-colored eyes, then X follows a binomial distribution with success probability p = 0.25 and number of trials n = 5.

The variance of a binomial distribution with these parameters is n p (1 - p), so the variance in this case would be

5 • 0.25 • (1 - 0.25) = 0.9375 ≈ 0.9
