Write b+c as 2-a, c+a as 2-b etc. and then row operations. It should not be too lengthy.

Is Q21 b? Just do casework. (Im replacing the 6 numbers on the die with 6 distinct colours). If there is 1 colour on all die then 6 possibilities. If there are 2 colours, (6 choose 2) gives us number of pairs of colours. Let the colours we have chosen to be on the die be X and Y. We can let the colours on any die be one of two possible colours so total configurations is 2^5. But we have also included the cases where the die have only one colour, so we need to subtract 2. Answer is 6 + (6 choose 2) * ( (2^5) - 2)

Thanks! can you help with number 28? I’m weak there…

For Q 28 as AX=0
Then the eqn either have trivial solns or non trivial soln as x=7 is given then det(A) should be 0 using this you can find value of K now with the help of it do matrix multiplication forms liner eqn of y and z solve and get your ans…

what’s the answer coming as? I’m getting BC
