Anumber from 1 to 10 is chosen at random what is the probability of choosing a 4 or an odd number

Probably to get a 4 or 1,3,5,7,8 so is the probability of getting 1,3,4,5,7,8 so answer is 6/10=3/5

6/10 or 0.6 or 60%

Step-by-step explanation:

The options for numbers are 1,2,3,4,5,6,7,8,9,and 10. There are 5 odd numbers from 1-10, 1,3,5,7, and 9. This woud be 50/50 odds. If you add four as an option, there would be 6 numbers, 1,3,4,5,7, and 9. the odds would be 6/10 which would be 60%.

you never say the total so we cant find the percentage used for petrol

step-by-step explanation:

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0
