tonal.​

Answer 1

Answer:

1.

number of prime numbers >7 is 7(in this case)

therefore

p(getting prime numbers greater than 7) =7/30

*explanation*

as it says greater than 7 we cannot count 7

the prime numbers are 11,13,17,19,23,27,29

2.

numbers not having perfect square =2,3,5,6,7,8,10,11,12,13,14,15,17,18,19,20,21,22,23,24,26,27,28,29,30

P(getting not aperfect square)=25/30

=5/6
