$A$ card is drawn at random from a pack of $52$ cards. The probability of this card being a red card or a queen is:

The three ships namely $A$,$B$ and $C$ sail from India to Africa. If the odds in favour of the ships reaching safely are $2:5$,$3:7$ and $6:11$ respectively,then the probability of all of them arriving safely is

For two given events $A$ and $B$,$P(A \cap B)$ is:

Given two independent events $A$ and $B$ such that $P(A) = 0.3$ and $P(B) = 0.6$. Find $P(\text{neither } A \text{ nor } B)$.

$A$ card is drawn from a pack of $52$ cards. Find the probability that the card will be a queen or a heart.

The probabilities of two events $A$ and $B$ occurring are $0.25$ and $0.50$ respectively. The probability of both events occurring simultaneously is $0.12$. Find the probability that neither event occurs.
