The probability of obtaining a sum of $8$ in a single throw of two dice is:

The chance of India winning the toss is $3/4$. If it wins the toss,then its chance of victory is $4/5$,otherwise it is only $1/2$. Then the chance of India's victory is

The probability of an event $A$ occurring is $0.5$ and that of $B$ is $0.3$. If $A$ and $B$ are mutually exclusive events,find the probability that neither $A$ nor $B$ occurs.

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

There are $n$ letters and $n$ addressed envelopes. The probability that all the letters are not kept in the right envelope,is

Two dice are thrown simultaneously. What is the probability of obtaining a multiple of $2$ on one of them and a multiple of $3$ on the other?
