Answer 1

To find the probability of spinning a 1 and tossing a head using the spinner and coin, we need to determine the total number of possible outcomes as well as the number of favorable outcomes.

Step 1: Count the possible outcomes

1. Spinner outcomes: The spinner has 5 sections (1, 2, 3, 4, 5).
2. Coin outcomes: The fair coin has 2 outcomes (Heads (H) or Tails (T)).

Thus, the total number of possible outcomes when spinning the spinner and tossing the coin is:

$$\text{Total outcomes}=\text{Number of spinner outcomes}\times \text{Number of coin outcomes}=5\times 2=10$$

Step 2: Count the favorable outcomes

The favorable outcome for this problem is spinning a 1 and tossing a head, which is represented as:

• $1,H$

There is only 1 favorable outcome in this case.

Step 3: Calculate the probability

The probability $P$ of an event is calculated using the formula:

$$P(\text{event})=\frac{\text{Number of favorable outcomes}}{\text{Total number of possible outcomes}}$$

Substituting the values we have:

$$P(\text{spinning a 1 and tossing a head})=\frac{1}{10}$$

Final Answer

The probability of spinning a 1 and tossing a head is $\frac{1}{10}$.
