$A$ number is chosen at random from the first ten natural numbers. The probability that the number is odd and a perfect square is

$A$ pair of dice is thrown. If $5$ appears on at least one of the dice,then the probability that the sum is $10$ or greater is:

There are $3$ urns $A, B$,and $C$. Urn $A$ contains $4$ red balls and $3$ black balls. Urn $B$ contains $5$ red balls and $4$ black balls. Urn $C$ contains $4$ red balls and $4$ black balls. One ball is drawn from each of these urns. What is the probability that the $3$ balls drawn consist of $2$ red balls and $1$ black ball?

Out of $5$ girls and $3$ boys,$4$ children are to be randomly selected for a quiz contest. What is the probability that all the selected children are girls?

Two dice are thrown simultaneously. What is the probability of getting two numbers whose product is even?
