A dice is thrown six times, it being known that each time a different digit is shown. The probability that a sum of 12 will be obtained in the first three throws is `5//24` b. `25//216` c. `3//20` d. `1//12`

A dice is thrown. The probability that the first time 1 occurs at the even throw is

A die is thrown three times and the sum of the 3 numbers shown is 15. The probability that the first throw was a four, is

Two dice are thrown at the same time. Find the probability that the sum of the two numbers appearing on the top of the disc is: 12

Two dice are thrown together. The probability that a lest one will show its digit greater than 3 is a. 1/4 b. 3/4 c. 1/2 d. 1/8

If three six-faced fair dice are thrown together, find the probability that the sum of the numbers appearing on the dice is 12.

A six-faced dice is so biased that it is twice as likely to show an even number as an odd number when thrown. It is thrown twice, the probability that the sum of two numbers thrown is even is 1//12 b. 1//6 c. 1//3 d. 5//9

A six-faced dice is so biased that it is twice as likely to show an even number as an odd number when thrown. It is thrown twice, the probability that the sum of two numbers thrown is even is 1//12 b. 1//6 c. 1//3 d. 5//9

A box contains 24 identical balls of which 12 are white and 12 are black. The balls are drawn at random from the box one at a time with replacement. The probability that a white ball is drawn for the 4th time on the 7th draw is 5//64 b. 27//32 c. 5//32 d. 1//2

Two dice are thrown. If it is known that the sum of the numbers on the dice was less than6, the probability of getting a sum 3 is a. 1/(18) b. 5/(18) c. 1/5 d. 2/5
