Answer 1

Step-by-step explanation:

1a) Possibility of two digit number=21

Total outcomes possible=30

Probability =

$\frac{21}{30} = \frac{7}{10}$

b) Possibility of perfect square=5 (1,4,9,16,25)

Total outcomes possible=30

Probability=

$\frac{5}{30} = \frac{1}{6}$

c) Possibility of number divisible by 5=6 (5,10,15,20,25,30)

Total outcomes possible=30

Probability=

$\frac{6}{30} = \frac{1}{5}$
