The point P(-6, -3) is reflected in line y + 3 = 0 to point P'. The co-ordinates of point P' are :

1. (-6, 3)

2. (-6, -3)

3. (6, 3)

4. (6, -3)

The solution set for -3 < x - 2 ≤ 9, x ∈ Z (integers) is :

1. {0, 1, 2, 3, 4, ………, 11}

2. {1, 2, 3, 4, ……., 10}

3. {-1, 0, 1, 2, 3, ……, 10}

4. {1, 2, 3, 4, 5, ……., 11}

If 55% of the population of a small town is purely vegetarian, 36% of the population is purely non-vegetarian and the rest are both. The probability, that a person chosen at random from the town is vegetarian and non-vegetarian both, will be :

1. 0.91

2. 0.55

3. 0.36

4. 0.09
