Question

Which event is most likely to happen?

A) selecting a vowel from the word RADIATION
B) turning ‘heads’ on a flipped coin
C) picking a blue ticket from a hat containing 8 red and 5 blue tickets

Answer 1

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)`

`=(5)/(9) =0.56`

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`

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`

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.
