The probability of getting a winning scratch off ticket is 4 out of 10. If Dan buys 25 tickets, how many of those would you expect to be winning tickets?
A. 10 tickets
B. 11 tickets*
C: 14 tickets
D: 15 tickets
4/10 = x/25
100 = 10x
10 = x
Thank you so much Ms. Sue your awesome! :)
:-) You're very welcome, Dejavu
Wait so the answer is 10?
To find the number of winning tickets Dan would be expected to have, we can use the probability of winning along with the number of tickets he bought.
The probability of winning a scratch off ticket is 4 out of 10, which can be written as a fraction as 4/10 or as a decimal as 0.4.
To find the expected number of winning tickets, we multiply the probability of winning by the number of tickets bought.
So, the expected number of winning tickets = 0.4 * 25 = 10.
Therefore, we would expect Dan to have 10 winning tickets out of the 25 that he bought.
