Respuesta :
the probability that a ticket is randomly chosen
will award a larger prize can be solved knowing the probability of each event. Since
the probability of a winning ticket is 6/ 10 then 1/3 is a larger prize. So for
every 10 there 2 larger prize. So the probability that a ticket is randomly chosen
will award a larger prize is 2/10 or 1/5
[tex]Answer: P(\text{a ticket is randomly chosen will award a large prize)}=\frac{2}{21}[/tex]
Since we have given that
Total number of tickets =10
Number of winning tickets =6
[tex]\text {Possibility of getting a winning ticket }=^{10}C_6[/tex]
In which one out of every three awards is a large prize
so,
[tex]\text{ Possibility of getting a large prize }=^6C_3[/tex]
Now,
[tex]P(\text{a ticket is randomly chosen will award a large prize)}=\frac{^6C_3}{^{10}C_6}\\\\=\frac{20}{210}\\\\=\frac{2}{21}[/tex]
[tex]P(\text{a ticket is randomly chosen will award a large prize)}=\frac{2}{21}[/tex]
