Winning the jackpot in a particular lottery requires that you select the correct five numbers between 1 and 34 and, in a separa

Marina CMI [18]

<h3>The probability of winning the lottery is $\frac{1}{10,295,472}$ </h3>

Step-by-step explanation:

Here, the total numbers in the jackpot = 1 to 34

Now, the number that needed to be drawn = 5

The number of ways , 5 number can be drawn from total 34 numbers :

$^{34} C _5 = \frac{34!}{5!(34-5)!} = 278,256$

Also, in separate draw, the correct number drawn = 1

So, the number of ways that can be done = 30 C 5 x 37

= 278,256 x 37 = 10,295,472

Now, P(win) = $\frac{\textrm{Total favorable attempts}}{\textrm{Total attempts}} = \frac{1}{10,295,472}$

Hence, the probability of winning the lottery is $\frac{1}{10,295,472}$

I am Lyosha [343]

Answer:

$559\frac{1}{5}$

Step-by-step explanation:

We want to determine the exact value that is 48% of 1165.

Now 48% = $\frac{48}{100}$

The term 'OF' means multiplication.

Therefore:

48% of 1165 = $\frac{48}{100}X 1165$

= $\frac{55920}{100}$

= $559\frac{1}{5}$

=559.2 in decimal form.

The exact value that is 48% of 1165

is given as $559\frac{1}{5}$ or 559.2 in decimal form.
