Answer: Hence, our required probability is $\dfrac{1}{386206920}$

Step-by-step explanation:

Since we have given that

Numbers in a lottery = 60

Numbers to win the jackpot = 7 numbers

We need to find the probability to hit the jackpot:

So, our required probability is given by

$P=\dfrac{^7C_7}{^{60}C_7}\\\\P=\dfrac{1}{386206920}$

This is a combination problem as we need to select 7 numbers irrespective of any arrangements.

Hence, our required probability is [tex]\dfrac{1}{386206920}[/tex

Simply cross-multiply about,

$\bf \cfrac{1}{2}=\cfrac{x}{4}\implies 4\cdot 1=2\cdot x\implies 4=2x\implies \cfrac{4}{2}=x\implies 2=x$
