The word '$UNIVERSITY$' is arranged randomly. Then the probability that both '$I$'s do not come together is:

$X$ speaks the truth in $60\%$ of cases and $Y$ in $50\%$ of cases. The probability that they contradict each other while narrating the same incident is

In a box,there are $8$ red,$7$ blue,and $6$ green balls. One ball is picked up at random. What is the probability that it is neither red nor green?

$A$ 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:

The sum of two positive numbers is $100$. The probability that their product is greater than $1000$ is

If $A$ and $B$ are two events such that $A \subseteq B,$ then $P\left( \frac{B}{A} \right) = $
