Answer:

Explanation:

Total possibilities when we a roll a die at a time are 6

given we should have four for first time and then three

let us assume we rolled the dice we may get 1,2,3,4,5,6(any of these) the probability to get 4 is

PROBABILITY=
$\frac{\textrm{FAVOURABLE CHANCES}}{\textrm{TOTAL CHANCES}}$

Favourable chances=1

Total chances=6

Probability=
(1)/(6)

the prabability to get 4 in first roll is
(1)/(6) .

let us assume we rolled the dice for second time again we may get 1,2,3,4,5,6(any of these) the probability to get 3 is

Favourable chances=1

total chances=6

probability=
(1)/(6)

the probability to get 3 in second roll irrespective of first one is
(1)/(6)

the probability to get 4 in first time and then 3 is

The probability to occur both events at a time is multiplication of individual probabilities

So,

probablility to get 4 in first roll=
(1)/(6)

probability to get 3 in second roll=
(1)/(6)

probability to occur both at a same time is =
(1)/(6)

(1)/(6) =
(1)/(36)
