These are the probabilities of each event
- Flipping tails on each coin has a probability of 1/2, so the probability of 4 consecutive tails is
- If there is a winning option out of four, there are three losing options. So, the chance of picking a wrong option is
- You are already given the probability of C, so we just record it:
- You can't roll a 7 on a standard die, so the probability is 0
- Assuming a baby can be born on any day with the same probability, there is a
probability he's born on a weekend, since there are two weekend days out of 7 in a week
- There are 4 aces out of 52 cards in a standard deck, so the probability of picking an ace is
- The sun will pretty surely rise tomorrow, so its probability is 1
- This is quite ambiguous, since it's not a sentence that can be rigorously defined. The probability is surely high, since summer days are tipically hot, but how can we give an exact probability? What's the treshold for being hot?
- A standard die has three even numbers (2,4,6) and three odd numbers (1,3,5). So, there is a probability of
to roll an odd number
- Flipping two coins you can have the following outcomes: HH, HT, TH, TT. So, 3 times out of 4 you have at least one head, so the probability is
So, if you order this probabilities, you have your scale
