Expert verified

The probability of identifying 鈥渋nappropriate attire鈥� as a mistake is 0.5.

鈥淚nappropriate attire鈥� is identified as one of the biggest mistakes made by candidates in job interviews.

It is given that there is a 50-50 chance of this being identified as a mistake.

Probability is a value that lies in the range of 0 and 1 (both inclusive).

It has the formula

$P (E) = \frac{Number of outcomes in favour of E}{Total number of outcomes}$

Let E be the event that 鈥渋nappropriate attire鈥� is identified as a mistake.

There is a 50-50 chance that event E happens. It meansthe chance of this event is 50 in 100 trials (subjects鈥� response).

In decimal, the probability value is

$P (E) = \frac{50}{100} = 0.5$

Therefore, the probability of 鈥渋nappropriate attire鈥� being identified as a mistake is 0.5.
