Answer 1

Answer:

$a)\ please\ see\ anambsis$

$b)\ The\ maximum\ number\ is\ 7.$

$c)\ \frac{5}{9}$

Step-by-step explanation:

$b)\ In\ odder\ from\ smallest\ to\ langst:\ 1,\ 2,\ 3,\ 3,\ 3,\ 4,\ 4,\ 4,\ 4,\ 4,\\ 5,\ 5,\ 6,\ 6,\ 6,\ 6,\ 7,\ 7)$

$Fiom\ the\ order,\\ the\ maximum\ number\ is\ 7$

$c)\ Number\ less\ thar\ 5: \ 2,\ 3,\ 4,\ 4,\ 4,\ 1,\ 3,\ 4,\ 3,\ 4_arcording\ to\ the\ table?$

   $\therefore10\ students\ spend\ not\ move\ than\ 5\ houks$

   $\therefore\ Probability\ is\ \frac{10}{18}=\frac{5}{9}$

I hope this helps you
