$5$ persons $A, B, C, D$ and $E$ are in a queue at a shop. The probability that $A$ and $E$ are always together is:

One bag contains $5$ white and $3$ black balls and a second bag contains $2$ white and $4$ black balls. One ball is drawn from the first bag and placed unseen in the second bag. What is the probability that a ball now drawn from the second bag is black?

Out of $30$ consecutive numbers,$2$ are chosen at random. The probability that their sum is odd,is

$A$ draws two cards with replacement from a pack of $52$ cards and $B$ throws a pair of dice. What is the chance that $A$ gets both cards of the same suit and $B$ gets a total of $6$?

From a pack of $52$ playing cards,three cards are drawn at random. Find the probability of drawing a king,a queen,and a jack.

$2$ dice are thrown. Find the probability of getting an odd number as the sum.
