Answer:
what are you calculating here
Step-by-step explanation:
Two sets (or three technically)
sets {2, 4, 6, 8, 10} & {8,9,10}
The probability of one of the above numbers because it is a union of those two vars/sets so numbers from either set go
{2, 4, 6, 8, 9, 10}
Thats 6 of the 10 numbers
6/10
.6

Step-by-step explanation:

x + 3 /

8x +22
-(8x + 24)

68*x/100=48
=> 68*x=4800
=> x=4800/68
=> x~=70.58
P.S: * means multiply, ~= means approximation, / means divide
