2 If a hockey team loses 33% of the games they play, what is the probability that this team will win exactly 10 games out of the

Gekata [30.6K]

They lose 33% of games i.e 0.33
They win 67% of games i e 0.67

P(A)=0.33
P(A')=0.67

Now

They win from 15games=10
They lose=5

The required probability

$\\ \rm\rightarrowtail P(A')^{10}\times P(A)^5\times ^{15}C_{10}$

$\\ \rm\rightarrowtail (0.33)^{5}\times (0.67)^{10}\times \dfrac{15!}{5!10!}$

$\\ \rm\rightarrow 0.0039(0.0182)\times\dfrac{15(14)(13)(12)(11)10!}{5!10!}$

$\\ \rm\rightarrowtail 0.00007098\times \dfrac{360360}{120}$

$\\ \rm\rightarrowtail 0.00007098(3003)$

$\\ \rm\rightarrowtail 0.213$

So probability

0.213(100)=21.3%

Evaluate:<br> -9 + 25 - (-10) + (-6)

Minchanka [31]

-9 is a negative number, so plus 25, it would be 16. The minus sign and the negative sign of -10 cancel out, so it is plus 10, ending up with 26. Finally, the + and - becomes negative (positive times negative equals negative), so it is -6 and you’ll end up with a final answer of 20.
