Suppose the odds against winning the lottery as 48,000,000 to 1. What is the probability of the event of winning the lottery giv
kupik [55]

The probability according to the given scenario will be "\frac{1}{48,000,001}".

According to the question:

  • The odds against winning the lottery are 48,000,000 to 1.
  • Favorable outcome = 1

→ The total outcome will be:

= 48,000,000 +1

= 48,000,001

As we know,

→ P(E) = \frac{Favorable \ outcomes}{Total \ outcomes}

By putting the values, we get

→           =\frac{1}{48,000,001}

Thus the above response is right.

an electrician can wire on average 4.5 houses in a week.how many months will it take her to wire 55 houses if she wires the same
Roman55 [17]
If you know how to divide by decimal you have to divide 55 ÷ 4.5 and you would get 12 but if you don't know keep multipling a number times 4.5 but overall if you don't want to do all the work the answer is going to be (55×4.5=12 or 4.5×12=55— 12 houses)

Alex73 [517]

let's firstly convert the mixed fraction to improper fraction and then divide.

\bf \stackrel{mixed}{2\frac{1}{2}}\implies \cfrac{2\cdot 2+1}{2}\implies \stackrel{improper}{\cfrac{5}{2}} \\\\[-0.35em] ~\dotfill\\\\ \cfrac{5}{2}\div 4\implies \cfrac{5}{2}\div \cfrac{4}{1}\implies \cfrac{5}{2}\cdot \cfrac{1}{4}\implies \cfrac{5}{8}

A softball has a volume of 1256π cubic inches. Find the radius of the softball.
RSB [31]
\bf \textit{volume of a sphere}\\\\
V=\cfrac{4\pi r^3}{3}~~
\begin{cases}
r=radius\\
------\\
V=1256\pi 
\end{cases}\implies 1256\pi =\cfrac{4\pi r^3}{3}
\\\\\\
1256\pi (3)=4\pi r^3\implies \cfrac{1256\pi (3)}{4\pi }=r^3\implies 942=r^3\implies \sqrt[3]{942}=r
