Solution: To find which event is most likely to happen, we need to find the probability of each event.
A) selecting a vowel from the word RADIATION
There are 9 letters in the word RADIATION. And there are 5 vowels in the given word.
Now the probability of selecting a vowel from the word RADIATION is:
P(Vowel) =
![(Number of vowels )/(Total Number of letter)](https://img.qammunity.org/2019/formulas/mathematics/college/vd3hlrz1g7mro42ix12h0i4lt5blmlm7pm.png)
![=(5)/(9) =0.56](https://img.qammunity.org/2019/formulas/mathematics/college/nfvyoy8lx8krhhlzvbtg5nz6tfw18byn1c.png)
B) turning ‘heads’ on a flipped coin
We know that probability of getting heads on a flipped coin is:
P(heads) =
![(1)/(2) =0.5](https://img.qammunity.org/2019/formulas/mathematics/college/i7thu0aqnbakjcrlta76zlhr349xzz8qd7.png)
C) picking a blue ticket from a hat containing 8 red and 5 blue tickets
The probability of picking a blue ticket from a hat containing 8 red and 5 blue tickets is:
P(picking a blue ticket)
![=(5)/(13)=0.38](https://img.qammunity.org/2019/formulas/mathematics/college/h1s8a3soej71ln2jzn3ldsm03prfe7jnlr.png)
We clearly see the event "selecting a vowel from the word RADIATION" has the highest probability. Therefore the event "selecting a vowel from the word RADIATION" is most likely to happen.
