Question
Which number cannot represent a probability?
Options
`2/3`
1.5
15%
0.7
`15/10`
Solution
`bb(15/10)` or 1.5
Explanation:
The probability of any event is Probability = `"Favorable outcomes"/"Total outcomes"`
We know that
0 < Favourable outcomes > Total outcomes
`0 < "Favorable outcomes"/"Total outcomes" < 1`
0 < Probability < 1
It means the probability of any event lies between 0 to 1.
Since 1.5 > 1, therefore cannot represent a probability.
Notes
1.5 and `15/10` Both options are correct; students can select the option according to their option given in the paper.
