A dice is thrown once, If getting a six, is a success, then find the probability of a failure.

A pair of dice is thrown 6 xx.If getting a total of 7 is considered a success,find the probability of atleast five successes.

A pair of dice is thrown 3 times. If getting a doublet is considered a success, find the probability of two successes.

A pair of dice is thrown 4 xx.If getting a doublet is considered a success,find the probability of two successes.

(i) A die is thrown 7 times. If getting an "even number" is "success", find the probability of getting at least 6 successes. (ii) A die is thrown 8 times. If getting an "even number" is a "success", find the probability of getting at least 7 successes.

(i) A die is thrown 5 times. If getting an 'odd number' is success, find the probability of getting at least 4 successes. (ii) A die is thrown 6 times. If getting an 'odd (even) number' is a success, what is the probability of : (I) 5 successes (II) at least 5 successes (III) at most 5 successes (IV) no success ? (iii) A die is thrown 10 times. If getting an even number is considered a success, find the probability of at least 9 successes.

A pair of dice is thrown 4 times. If getting a doublet is considered a success, find the probability distribution of number of successes. Also, find the mean and variance of number of successes.

A pair of dice is thrown 4 xx.If getting a doublet is considered a success,find the probability distribution of number of successes.

A pair of dice is thrown 4 xx.If getting a doublet is considered a success,find the probability distribution of the number of successes and hence find its mean.

If pair of dice is thrown 4 xx.If getting a doublet is considered a success,find the probability distribution of the number of doublets in three throws of a pair of dice and hence find its mean.

A pair of dice is thrown 4 times. If getting a doublet is considered as a success, (i) find the probability of getting a doublet (ii) hence, find the probability of two succeses.
