n(s)=30

LetA be the event Of getting non divisible by 3

A = 1, 2, 4, 5, 7, 8, 10, 11, 13, 14, 16, 17, 19, 20, 22, 23, 25, 26, 28, 29.

n(A) = 20

P(A) = 20/30 = 2/3

Let B be the event of getting prime number greater than 7

B = 11, 13, 17, 19, 23, 29

N(B) = 6

P(B) = 6/30 = 1/5.

Let c be the getting not perfect square

C = 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.

n(c) = 25

P(c) = 25/30 = 5/6.

(i) There numbers are 20 numbers not divisible by 3 from 1 to 30. So the probability is 20/30 or 2/3 or 0.66 (ii) There are 6 such numbers so the probability is 6/30 or 1/5 or 0.2 (iii) There are 25 such numbers, so the probability is 25/30 or 5/6 Or 0.83

Given p/h = 1/2. So b =(2x2-1x1) ^1/2 = root3. So cos A = b/h = (root 3)/2
