Candice own a chocolate shop. One of her most popular products is a box of 40 assorted chocolates, 5 of which contain nuts.

If a person selects two chocolates at random from the box, what is the probability that

i) both of the chocolate contains nuts

ii) at least one of the chocolates contains nuts

iii) only one of the chocolates contains nuts

iv) neither of the chocolates contains nuts?

Any help is MUCH MUCH MUCH appreciated
