There are 10 tickets in the box, 3 of them are winning. find the probability that you take one ticket from the box and it will be winning ticket, then you take second ticket and it will be also winning ticket. taken ticket is not returned back to the box. hint: p(a and b.= p(a)×p(b)

Which compound inequality could be represented by the graph?
