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%

find the mean, median, and mode of the data set. round to the nearest tenth. 7,7,14,15,4,1,7,2,15,9,5

Arisa [49]

Here is the mean, median, and mode:

Mean: 1+2+4+5+7+7+7+9+14+15+15 = 86/11 ≈ 7.82
Median: 7
Mode: 7

To find the mean add up all the numbers and divide by the number of numbers

To find the median you just keep on crossing of numbers left to right until you get the middle number

To find the mode just look at which number is most commonly seen

Hope this helps!
