Solution

The correct option is A 30%
There is a 60% chance that a customer purchases the bike, and 13rd out of those purchase accessories.
The simulator works with digits 1 to 5.60% of 5 is 3 digits.
Let us take 1, 2, and 3 as bikes sold.
(13)rdout of those buy accessories, hence only 1 represents accessories that were purchased along with bikes.

Also,
Let the ones digit represent accessories brought and the tens place represent bikes purchased.

6 out of 50 fits the criteria, so

Expected probability =650×100

=12%

The expected probability of a customer buying a bike as well as accessories is 12%.
