Math Problem Statement
A coin is tossed and a die is rolled. Find the probability of getting a head and a number greater than 1.
Solution
To solve the problem, we analyze the events step-by-step:
-
Coin Toss: A coin has two outcomes: Head (H) and Tail (T).
- Probability of getting a Head = .
-
Die Roll: A standard die has six outcomes: {1, 2, 3, 4, 5, 6}.
- The numbers greater than 1 are {2, 3, 4, 5, 6}.
- Probability of rolling a number greater than 1 = .
-
Combined Event: The events are independent, so the probability of both occurring (a head from the coin and a number greater than 1 from the die) is the product of their individual probabilities:
Final Answer:
The probability of getting a head and a number greater than 1 is .
