If a leap year is selected at random,what is the chance that it will contain $53$ Tuesdays?

If a number $x$ is drawn randomly from the set of numbers $\{1, 2, 3, \ldots, 50\}$, then the probability that the number $x$ satisfies the inequation $x + \frac{10}{x} \leq 11$ is

$A$ die is tossed thrice. Find the probability of getting an odd number at least once.

One card is drawn from a well-shuffled deck of $52$ cards. If each outcome is equally likely,calculate the probability that the card will be a black card (i.e.,a club or a spade).

If a point $A(x, y)$ lies in the region bounded by the $y$-axis,straight lines $2y+x=6$ and $5x-6y=30$,then the probability that $y < 1$ is

Let $S$ be the sample space of all five-digit numbers. If $p$ is the probability that a randomly selected number from $S$ is a multiple of $7$ but not divisible by $5$,then $9p$ is equal to.
