Sergeeva-Olga [200]

The probability that a certain hockey team will win any given game is 0.3723 based on their 13 year win history of 385 wins out
Whitepunk [10]

Answer:

0.1505 = 15.05% probability that the hockey team wins 6 games in November

Step-by-step explanation:

For each game, there are only two possible outcomes. Either the team wins, or it does not. The probability of winning a game is independent of winning other games. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

In which C_{n,x} is the number of different combinations of x objects from a set of n elements, given by the following formula.

C_{n,x} = \frac{n!}{x!(n-x)!}

And p is the probability of X happening.

The probability that a certain hockey team will win any given game is 0.3723

So p = 0.3723

12 games in November

So n = 12

What is the probability that the hockey team wins 6 games in November?

This is P(X = 6)

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

P(X = 6) = C_{12,6}.(0.3723)^{6}.(1-0.3723)^{6} = 0.1505

0.1505 = 15.05% probability that the hockey team wins 6 games in November

Harold paid 5% in sales tax on his new "smart fabric" warm-ups.
natita [175]

Answer:

The pre-tax price of "smart fabric" warm-ups is $745 .

Step-by-step explanation:

Let us assume that the pre-tax price of the "smart fabric" warm-ups be x .

As given

arold paid 5% in sales tax on his new "smart fabric" warm-ups.  

if harnold paid 37.25 in sales tax on the warm ups .

5% is written in the decimal form .

=\frac{5}{100}

= 0.05

Equations becomes

0.05 × x = 37.25

0.05x = 37.25

x = \frac{37.25}{0.05}

x = $745

Therefore the pre-tax price of "smart fabric" warm-ups is $745 .
