John throws a fair 6-sided die. What is the probability he will get a multiple of 2?
If it is a fair die, the probability is 5/6.
The probability of rolling a 4 when you throw once a fair die is: P(4) = 1/6.The probability of not rolling a 4 when you throw once a fair die is: P(NO 4) = 5/6.If you roll a fair die four times, the probability of rolling a four on only the secondthrow is:P(NO 4, 4, NO 4, NO 4) = (5/6)(1/6)(5/6)(5/6) = 0.096450617... ≈ 9.6%
Assuming that it is a fair die, the answer is 5/9.
If the die is fair, the answer is 3003/32768 = 0.0624 or approx 1 in 16.
