1.Suppose a box contains three cards, one with both sides white, one with both sides black, and one with one side white and the other side black. If you pick a card at random, and the side facing you is white, then the probability that the other side is white is 1/2.

2.A gardener throws 18 seeds onto an equilateral triangle shaped plot of land with sides of length one metre. Then at least two seeds are within a distance of 25 centimetres.

can anyone help to solve which of the above statements are true.thank you.

    Is this homework? Hints: 1) write down a sample space and model. 2) find the area of the triangle, and then approximate (exact will be difficult) the minimum area needed by 18 seeds separated as given.2012-09-23

    i think problem 2 should not be called a probability problem.2012-09-23
