its 100 out of 1000
thanks soo much
Since they bought 100 tickets, the probability that they won't win is 1000 - 100 = ?
Stephanie gave the probability that they would win.
I hope this helps a little more. Thanks for asking.
To calculate the probability of not winning the raffle, we need to know the total number of tickets sold and the number of tickets Emily's parents purchased. From the information given, we know that 1,000 raffle tickets were sold at $2.00 each, and Emily's parents spent $200 on tickets.
First, let's find the number of tickets Emily's parents purchased. Since each ticket costs $2.00 and they spent $200 in total, we can calculate the number of tickets as follows:
Number of tickets = Amount spent / Cost per ticket = $200 / $2.00 = 100 tickets
So, Emily's parents purchased 100 raffle tickets.
Now, let's find the probability of not winning the raffle. To do this, we need to calculate the number of tickets that did not belong to Emily's parents. Subtract the number of tickets Emily's parents purchased from the total number of tickets:
Number of tickets not belonging to Emily's parents = Total number of tickets - Number of tickets purchased by Emily's parents = 1,000 - 100 = 900 tickets
The probability of not winning the raffle is given by:
Probability of not winning = Number of tickets not belonging to Emily's parents / Total number of tickets
Probability of not winning = 900 / 1,000
Simplifying the above fraction, we get:
Probability of not winning = 9 / 10
Hence, the probability that Emily's parents won't win the raffle is 9/10 or 0.9.
