00:00 - 00:59 | welcome to doubt NET question it was given to us was given a is equals to X belongs to Ek belongs to natural number and X is greater than 3% less than equal to 6 and we set is equal to X belongs to a g to whole number and X is less than four Soviet to find this all terms so first of all in the first option react to write this sets A and B roster form so roster form is tabular form so a is equals to X belongs natural number in Axis greater than 3 but less than equal to 6 this consists of term 4 5 and 6 also because there is equals to sin similarly be set is equals to X belongs to whole number and access less than 40 in whole number zero is also included so we get 2012 and only up to three sunao the second option that was given to us because we have to tell the value of a union B so a union b is equal to 0 1 2 3 4 5 and 6 when we add these to we get this is a union B similarly in third option BF |

01:00 - 01:59 | to find intersection b that is common number between them so a intersection b so there is no common number between them so this was = 25 similarly 4th option that was given to us that we have to find the value of a minus b so we have to subtract the elements of be from a so only so there is no element that was present in a so we get there is no element that that that was present in a was present in be so we get the elements of that is 45 in 6 from now the last 50 option that we want is B minus A so there is no common elements between them so the answer you should also equals to be that is 012 in 3 cities are the final answers think you |
