There are 10 marbles in a box which are marked with the distinct numbers from 1 to 10. If a marble is drawn, then what is the probability of getting prime numbered marble ?

There are 10 marble in a box which are marked with the distinct numbers from 1 to 10. A marble is drawn randomly. The probability of getting prime numbered marble is (a) 1/2 (b) 2/5 (c) 9/3 (d) 3/(10)

There are 10 marble in a box which are marked with the distinct numbers from 1 to 10. A marble is drawn randomly.The probability of getting prime numbered marble is (1)/(2) (b) (2)/(5)(9)/(3) (d) (3)/(10)

In a box, there are 20 marbles. Each marble is marked with a distinct number from 1 to 20. Find the probability of drawing a marble from the box which is marked with a number that is a perfect square.
