Well first of all, flipping a coin is not a 50/50 chance, it is a 49/51 chance favoring the side you started on. I would point out that the flipping of the coin seems to favor tails with 66 to 34, so it is reasonable to assume that the coin was flipped with tails side up more often than heads. First you need to add 66+34=100, the answer is B
Year 1 3000 x .007 = 21.00 Year 2 3021 x .007 = 21.15 Year 3 3042.15 x .007 = 21.30 Year 4 3063.45 x .007 = 21.44 Year 5 3084.89 x .007 = 21.59 Year 6 3106.48 x .007 = 21.75 Year 7 3128.23 x .007 = 21.90 Year 8 3150.13 x .007 = 22.05 _____
The die has a 2/6 chance of getting a number less than 3, simplified to 1/3 chance The coin has a 1/2 chance of getting heads Multiply the probabilities to get the probability of both happening,
