Solution

To find the probability of getting a head and a number greater than 5 when a coin is tossed and a die is rolled:

Step 1: Define the sample spaces

  • The coin can result in 2 outcomes: Head (H) or Tail (T).
  • The die can result in 6 outcomes: {1, 2, 3, 4, 5, 6}.

Thus, the total number of outcomes when combining both events is:

2×6=122 \times 6 = 12

Step 2: Favorable outcomes

  • A head (H) is one outcome from the coin.
  • A number greater than 5 on the die is one of two outcomes: {6}.

Thus, the favorable outcomes are:

  • (H, 6)

This is a single outcome.

Step 3: Probability calculation

The probability is the ratio of favorable outcomes to total outcomes:

P(Head and number > 5)=Favorable outcomesTotal outcomes=112P(\text{Head and number > 5}) = \frac{\text{Favorable outcomes}}{\text{Total outcomes}} = \frac{1}{12}

Final Answer:

112\boxed{\frac{1}{12}}
