$A$ box contains $10$ identical electronic components,of which $4$ are defective. If $3$ components are selected at random from the box in succession,without replacement,what is the probability that exactly two components of the selected components are defective?

$A$ card is drawn randomly from a pack of playing cards. The probability that it is neither an ace nor a king is:

In a single throw of $3$ dice,find the probability of getting a total of $17$ or $18$.

$2$ dice are thrown. Find the probability of getting a sum greater than $10$.

The probability of drawing a white ball from a bag containing $3$ black balls and $4$ white balls is:

$A$ box contains $2$ black,$4$ white,and $3$ red balls. One ball is drawn at random from the box and kept aside. From the remaining balls in the box,another ball is drawn at random and kept aside the first. This process is repeated until all the balls are drawn from the box. The probability that the balls drawn are in the sequence of $2$ black,$4$ white,and $3$ red is
