As one equation is already solved for a variable, in this case y, A is the correct demonstration of substitution
5y+30+2y<4y+8
5y+2y-4y<8-30
3y<-22
y<-22/3
To solve these, basically find out how many numbers satisfy your requirment, then divide that number by 10. Simplify your fraction and you have your probability.
probability of getting a 10: 1/10
probability of getting a 5: 1/10
probability of not getting 10: 9/10
probability of getting an odd number: 5/10
probability of getting a number less than 4: 3/10
probability of getting a number greater than 7: 3/10
Hope this helps, and muchas luck on your math!
