6 is right. 7, the fraction is right, but the equation doesn't make sense. It would be .25, not 2.5.
I'll work through 8 with you, and it should help with the rest. Okay, so you have 6 possible outcomes: 1, 2, 3, 4, 5, and 6. The question is "What's the probably of not getting a 5?" Well, the probability of getting a 5 is 1/6, so not getting a 5 would be 5/6 or about 83.3%
Answer:
3 units
Step-by-step explanation:
I'm not sure how to explain it but I hope it helps.
Car normally has 4 wheeles
motorcycles normall have 2 wheels
c=cars
m=motorcycles
4c+2m=98
c+m=30
multiply second equation by -2 and add to the original equaiton
-2c-2m=-60
4c+2m=98 +
2c+0m=38
2c=38
divide 2
c=19
sub
c+m=30
19+m=30
m=11
11 motorcycles
19 cars
