Math Problem help plss.....?

Question

1)There are 6 toffee, 14 caramel and 8 nut centered chocolates in a box How many chocolates do you have to pick to make sure you have a nut centered chocolate?

2) the Queen of Egypt was born in 69 bc and died in 39bc.
What year was that?

Tanx if you could help :)

Answer 1

1) Probability of picking 1 nut-centered chocolate = Number of nut-centered chocolates / Total Chocolates
Number of nut-centered chocolates = 8
Total = 6 + 14 + 8 = 28
So the proportion is 8/28 = 2/7

2) BC is Before Christ. There years go before 0 like in negative numbers. 69 BC comes before 39 BC. But the age is calculated the same method = 39 - 69 = -30. Modulus of (-30) = 30 years.

Answer 2

1) In the worst possible case, I would have to pick all of the caramel and all of the toffee before I can get a nut-centered chocolate. 6 toffee + 14 caramel = 20, plus one for the next selection.

Therefore, I would have to pick 21 chocolates to make sure I have a nut-centered chocolate.

2) To find out the age the Queen of Egypt died, treat 69bc as -69 and 39bc as -39. Subtract the bigger year from the smaller year.

-39 - (-69) = -39 + 69 = 30 years old.

Answer 3

21
