Justin’s teacher places a ticket with a student’s name in a jar each time they perform an act of kindness. At the end of the week the teacher will draw a ticket from the jar and award a prize. Justin has 13 tickets so far, with a total of 100 in the whole jar. His goal is to have 20 tickets, and he’s estimating the total number of tickets at that point would be about 200. What is the probability of him winning the drawing if he meets his goal?(1 point)

Answer 1

To find the probability of Justin winning the drawing if he meets his goal of having 20 tickets out of a total of 200 tickets, you would calculate the fraction of tickets he would have in relation to the total number of tickets:

20 tickets out of 200 tickets = 20/200 = 1/10

So, the probability of Justin winning the drawing if he meets his goal is:

1/10

Which is the same as:
