List all two-element sets in p({a, b,c, d})

note: this is discrete math, p stands for power set. explain if possible.

{a,b}, {a,c} , {a,d}, {b,c}, {b,d}, {c, d}

Step-by-step explanation:

If we have P({a, b, c, d}) where P is the power set, we know that there are 6 two elements sets in P (because this is the number of combinations of two elements taken from 4 elements,

These 6 sets would be: {a,b}, {a,c} , {a,d}, {b,c}, {b,d}, {c, d}

where r the answers

step-by-step explanation:

57.09 minus 7.0435 equals

step-by-step explanation:

just subtrach them both and u get the answer of 50.0465
