a. To solve this, we should make a combination

$\begin{gathered} nCr=\frac{n!}{r!(n-r)!} \\ 24P5=\frac{24!}{5!(24-5)!}=42504 \end{gathered}$

5 person committee can be chosen in 5100480 different ways

b. To find this probability (A), we should use the answer of the last question as the total cases, and the favourable cases will be the shown combinations

$P(A)=\frac{7C3\cdot17C2}{42504}$

Calculate the combinations

$\begin{gathered} 7C3=\frac{7!}{3!(7-3)!}=35 \\ 17C2=\frac{17!}{2!(17-2)!}=136 \\ P(A)=\frac{35\cdot136}{42504}=\frac{4760}{42504}=0.1120 \end{gathered}$

Natasha2012 [34]

Answer:

$3000

Step-by-step explanation:

I= PRT÷100

where,

I = interest = 900

T= 5

R/100 = 0.06

P = ?

I= PRT/100

900= P × 5 × 0.06

P = 900÷ 0.3

P= 3000
