To determine which event is most likely to happen, we need to analyze the probabilities of each event:

  1. Getting a 6 when rolling a single die once: There is 1 outcome (rolling a 6) out of 6 possible outcomes (1, 2, 3, 4, 5, 6), so the probability is \( \frac{1}{6} \).

  2. Getting a head from a single toss of a fair coin: There are 2 outcomes (heads or tails), so the probability is \( \frac{1}{2} \).

  3. Randomly picking a vowel letter from the English alphabet: There are 5 vowels (A, E, I, O, U) out of 26 letters in total, so the probability is \( \frac{5}{26} \), which is approximately \( 0.192 \).

  4. Randomly picking a consonant from the English alphabet: There are 21 consonants (the total 26 letters minus the 5 vowels), so the probability is \( \frac{21}{26} \), which is approximately \( 0.808 \).

Now, comparing the probabilities:

  • Rolling a 6: \( \frac{1}{6} \approx 0.167 \)
  • Getting heads: \( \frac{1}{2} = 0.5 \)
  • Picking a vowel: \( \frac{5}{26} \approx 0.192 \)
  • Picking a consonant: \( \frac{21}{26} \approx 0.808 \)

The event most likely to happen is randomly picking a consonant from the English alphabet.
