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

So

  • 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%

Answer:

<em>The correct option is:  C. x=6\sqrt{3}, y=12</em>

Step-by-step explanation:

The two angles of the triangle are given as 60° and 60°

As the sum of all three angle in any triangle is always 180°, so the measure of the third angle will be: 180°-(60°+60°) = 180° - 120° = 60°

Now each angle of the triangle is 60°, it means the triangle is equilateral.

The base of the triangle is given as 12. So, the length of each side will be 12.

That means, the value of y=12

Now in the left right triangle.....

Sin(60)=\frac{x}{y} \\ \\ \frac{\sqrt{3}} {2}=\frac{x}{12} \\ \\ 2x=12\sqrt{3} \\ \\ x=6\sqrt{3}

So, the value of x = 6\sqrt{3}
