Probability of non-occurrence i.e. she wins the first prize is
Answer:
At least 13 chocolates must be removed
Step-by-step explanation:
If there are three flavors, the probability of drawing 1 would be: 1
1/3 = 0.333
Which means, that every 3 attempts, theoretically you should do 1 of each, but how they ask for 5 chocolates of each would be:
3 * 5 = 15
At least 15 chocolates must be extracted to theoretically guarantee 5 chocolates each, but how we are interested in knowing is that a single flavor has 5 chocolates, so we discard the last two chocolates that represent the other two flavors
Therefore, for there to be safely 5 chocolates of the same flavor, at least 13 chocolates must be removed.
The equation is y=6.66666667x. This is because you get paid $6.66666667 per hour so you multiply that by the number of hours to get the total paid!
We would have
a + b = 360
a - 40 = b, so we solve as follows:
360-40=320,
320/2 = 160,
160 + 40 = 200.
Check: 200+160 = 360, so
200 is your answer.
Hope this helps and have a nice day:)
