Answer:
The number of black T-shirts in 110 experiments is 20.
Step-by-step explanation:
It is given that in 55 trials of the experiment, a black T-shirt was drawn 10 times.
Formula of probability:
[tex]P=\frac{\text{Favorable outcomes}}{\text{Total number of outcomes}}[/tex]
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
[tex]P=\frac{10}{55}[/tex]
[tex]P=\frac{2}{11}[/tex]
The number of black T-shirts that would be drawn in 110 times is
[tex]T=\frac{2}{11}\times 110=20[/tex]
Therefore the number of black T-shirts in 110 experiments is 20.
