Answer:
The number of black T-shirts in 110 experiments is 20.
Explanation:
It is given that in 55 trials of the experiment, a black T-shirt was drawn 10 times.
Formula of probability:

Since 55 trials of the experiment, a black T-shirt was drawn 10 times, therefore the probability of getting black T-shirts in 1 experiment is


The number of black T-shirts that would be drawn in 110 times is

Therefore the number of black T-shirts in 110 experiments is 20.
