Q. You roll a 6-sided die two times.What is the probability of rolling a 6 and then rolling a number greater than 5?Simplify your answer and write it as a fraction or whole number._____
Probability of Rolling a 6: The possible outcomes of rolling a 6-sided die are {1,2,3,4,5,6}. The probability of rolling a 6 is P(Rolling a 6)=Total outcomesFavorable outcomes=61
Probability of Rolling > 5: Since there is only one number greater than 5 on a 6-sided die, which is 6 itself, the probability of rolling a number greater than 5 is the same as the probability of rolling a 6. Therefore, P(\text{Rolling a number} > 5) = \frac{\text{Favorable outcomes}}{\text{Total outcomes}} = \frac{1}{6}
Probability of Rolling 6 and > 5: The probability of rolling a 6 and then rolling a number greater than 5 is the product of the two individual probabilities. This is because the two rolls are independent events. So, P(\text{Rolling a 6 and then Rolling a number > 5}) = P(\text{Rolling a 6}) \times P(\text{Rolling a number > 5})=61×61=361
