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}
