A die is thrown, find the probability of following events: A number less than or equal to one will appear,

Suppose that a die (with faces marked $1$ to $6$) is loaded in such a manner that for $K = 1, 2, 3…., 6$, the probability of the face marked $K$ turning up when die is tossed is proportional to $K$. The probability of the event that the outcome of a toss of the die will be an even number is equal to

Three coins are tossed once. Find the probability of getting atleast $2$ heads.

From a pack of $52$ cards two are drawn with replacement. The probability, that the first is a diamond and the second is a king, is
