Two cards are drawn without replacement from a well-shuffled pack. Find the probability that one of them is an ace of heart.

$A$ biased die is tossed and the respective probabilities for various faces to turn up are given below:

$Face$	$1, 2, 3, 4, 5, 6$
$Probability$	$0.1, 0.24, 0.19, 0.18, 0.15, 0.14$

If an even face has turned up,then the probability that it is face $2$ or face $4$ is:

Among $15$ players,$8$ are batsmen and $7$ are bowlers. Find the probability that a team is chosen of $6$ batsmen and $5$ bowlers.

One ticket is drawn at random out of $30$ tickets numbered from $1$ to $30.$ Find the probability that the number on the ticket is a multiple of $5$ or $7.$

Study the given information carefully to answer the question that follows. An urn contains $4$ green,$5$ blue,$2$ red,and $3$ yellow marbles. If $3$ marbles are drawn at random,what is the probability that at least $1$ is yellow?

If $E$ and $F$ are events with $P(E) \le P(F)$ and $P(E \cap F) > 0,$ then
