a. In how many ways can you choose three flags from a collection of seven different flags? b. Once you choose three flags, in how many different orders can you arrange them? c. Writing You want to arrange three flags from a group of seven. Explain how you can use \(_{7} \mathrm{C}_{3} \cdot 3 !\) to create the permutation formula.
Find the value of \(7 !\)
Simplify each expression. $$ _{5} \mathrm{C}_{2}+_{5} \mathrm{C}_{3} $$
Genetics A family has five children. Assume that the probability of having a boy is \(0.5 .\) Write the term in the expansion of \((b+g)^{5}\) for each outcome described. Then evaluate each probability. \(\begin{array}{llll}{\text { a. exactly } 3 \text { boys }} & {\text { b. exactly } 4 \text { boys }} & {\text { c. exactly } 4 \text { girls }}\end{array}\)
