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

$A$ bag contains $3$ white,$2$ blue,and $5$ red balls. One ball is drawn at random from this bag. The probability that the ball drawn is not red is

Two fair dice are rolled. The probability of the sum of digits on their faces being greater than or equal to $10$ is

The probability of happening at least one of the events $A$ and $B$ is $0.6$. If the events $A$ and $B$ happen simultaneously with a probability of $0.2$,then $P(\bar{A}) + P(\bar{B}) = $

The probability that at least one of the events $A$ and $B$ occurs is $3/5$. If $A$ and $B$ occur simultaneously with probability $1/5$,then $P(A') + P(B')$ is (in $/5$)

The probability that a leap year selected randomly will have $53$ Sundays is
