The probability of having a winning raffle ticket is 20%. If you bought 50 tickets, how many winning tickets should you expect to have?



Answer :

[tex] \frac{20}{100} = \frac{x}{50} [/tex]
Let's solve for x:
100x=1000
Divide by 100
x=10
You should expect to win 10 times.
10because if you do 1/5=x/50 then you get 10 ...............................................................................................................
