Find the probability of each event.
Spinning red on a spinner with equally sized red, blue, yellow, and green sectors, and flipping a coin that lands tails up
prob =(1/4)(1/2)
= 1/8
To find the probability of each event, we need to determine the number of favorable outcomes and the total number of possible outcomes.
1. Spinning red on a spinner:
The spinner has four equally sized sectors (red, blue, yellow, and green). Since we want to determine the probability of spinning red, there is only one favorable outcome (the red sector) out of the total four possible outcomes (red, blue, yellow, and green).
Probability of spinning red = Number of favorable outcomes / Total number of possible outcomes
= 1/4
= 0.25 (or 25%)
2. Flipping a coin that lands tails up:
A coin has two sides - heads and tails. For flipping a coin and getting tails up, there is one favorable outcome (the tails side) out of the total two possible outcomes (heads or tails).
Probability of flipping tails = Number of favorable outcomes / Total number of possible outcomes
= 1/2
= 0.5 (or 50%)
Therefore, the probability of spinning red on the spinner is 0.25 (25%) and the probability of flipping a coin that lands tails up is 0.5 (50%).
To find the probability of each event, we need to know the total number of possible outcomes and the number of favorable outcomes for each event.
1. Event: Spinning red on a spinner with equally sized red, blue, yellow, and green sectors.
- Total number of possible outcomes: 4 (red, blue, yellow, and green)
- Number of favorable outcomes: 1 (red)
- Probability of spinning red: Number of favorable outcomes / Total number of possible outcomes
= 1 / 4
= 1/4 or 0.25 (25%)
2. Event: Flipping a coin that lands tails up.
- Total number of possible outcomes: 2 (heads and tails)
- Number of favorable outcomes: 1 (tails)
- Probability of getting tails: Number of favorable outcomes / Total number of possible outcomes
= 1 / 2
= 1/2 or 0.5 (50%)
Therefore, the probability of spinning red on the spinner is 1/4 or 0.25 (25%), and the probability of flipping a coin and getting tails is 1/2 or 0.5 (50%).
