Question 880772
Choosing the first ticket, there are 25 tickets greater than 25 and 50 total.
{{{P(1)=25/50=1/2}}}
Choosing the second ticket, there are 24 tickets greater than 25 and 49 total.
{{{P(2)=24/49}}}
Choosing the third ticket, there are 23 tickets greater than 25 and 48 total.
{{{P(3)=23/48}}}
So these are all independent events,
{{{P(1,2,3)=(1/2)(24/49)(23/48)}}}
{{{P(1,2,3)=(1/2)(1/49)(23/2)}}}
{{{P(1,2,3)=23/196}}}
