and one gray-haired (litter 1), and the other with three brown-haired and two gray- haired (litter 2).We select a litter at random and then select an offspring at random from the selected litter. (a) What is the probability that the animal chosen is brown-haired? (b) Given that a brown-haired offspring was selected, what is the probability that the sampling was from litter 1?

Simplify. Assume all variables are positive. \[ \frac{b^{\frac{5}{4}}}{b^{\frac{7}{4}}} \]

Part 1 of 2 (a) Find the rational zeros and then the other zeros of the polynomial function \( f(x)=x^{3}-91 x+90 \); that is, solve \( f(x)=0 \). (b) into linear factors. (a) Select the correct choice below and fill in any answer box(es) within your choice. (Type integers or fractions. Use a comma to separate answers as needed. Type exact answers, using radicals as needed. Expres B. The rational zero(s) is/are \( \square \), and the other zero(s) is/are C. There are no rational zeros. The other zeros are
