Answer:

1. The probability that the T-shirt will be grey :-

=》

$\frac{2}{20}$

=》

$\frac{1}{10}$

=》

$0.1$

hence, the probability of grey t-shirt is 0.1

2. The probability that the T-shirt will not be red :-

=》

$1 - \frac{4}{20}$

=》

$1 - \frac{2}{10}$

=》

$1 - 0.2$

=》

$0.8$

The probability that the T-shirt will not be red is

0.8

3. He takes one of his blue T-shirts at random.

What is the probability that the T-shirt is light blue

total blue t-shirts = 5

so, the probability of choosing light blue t-shirt is

=》

$\frac{1}{5}$

=》

$\frac{2}{10}$

=》

$0.2$

hence, the probability of choosing light blue t-shirt is 0.2
