Answer:

The answer is \frac{15}{31}

Step-by-step explanation:

In order to determine the probability, we have to know the classical probability.

Classical probability is a simple form of probability that has equal odds of something happening. The probability of a simple event happening is the number of times the event can happen, divided by the number of possible events.

Given:

A=amount of favorable outcomes

B=amount of possible outcomes

E=event

P(E)=\frac{A}{B}

So that, we have to determine:

the amount of possible outcomes:

B=15 boys + 16 girls =31

the amount of favorable outcomes:

A=15 boys

E= boy's name is drawn at random event

P(E)=\frac{15}{31}

Finally, the answer is \frac{15}{31}

r = Julio's hourly rate

1.4 * r = Julios over 30 hours rate.


last week he worked 30 hours at regular rate, 30r, and 5 extra hours at 1.4r, we happen to know all that is really $436.60.


\bf 436.6=\stackrel{\stackrel{\textit{30 hours}}{\textit{regular rate}}}{30r}+\stackrel{\stackrel{\textit{5 hours}}{\textit{overtime rate}}}{5(1.4r)}\implies 436=30r+7r\\\\\\436.6=37r\implies \cfrac{436.6}{7}=r\implies 62.37148571\approx r


b = Maggie's brother's age

m = Maggie's age


\bf \stackrel{\textit{Maggie's brother}}{\boxed{b}}=\stackrel{\textit{3 less than twice \underline{m}}}{2m-3}\hspace{10em}\stackrel{\textit{their sum is 24}}{b+m=24}\\\\ \rule{31em}{0.25pt}\\\\ b+m=24\implies \boxed{2m-3}+m=24\implies 3m=27 \\\\\\ m=\cfrac{27}{3}\implies m=9
