Justin tease teacher places a ticket with a student's name in each car each time they perform an act of kindness at the end of the week the teacher will draw a ticket from the car and a war to prize Justin has 13 tickets so far what a total of $100 in the holes are his goal is to have 20 tickets he is estimate in the total of tickets at that point would be about 200 what is the probability of him winning a drawn if he meets his goal 1/10 13/100-150
To find the probability of Justin winning a prize when he meets his goal of having 20 tickets, we need to calculate the probability of his ticket being drawn out of 20 tickets total.
If there are 20 tickets and Justin has 13 tickets, then the probability of his ticket being drawn is: 13/20 = 0.65
Therefore, the probability of Justin winning a prize when he meets his goal is 0.65 or approximately 65%.
