Answer:
Step-by-step explanation:
<u>Given</u>
<u>8 total balls</u>
- p(r and r) = 5/8*4/7 = 5/14
- p(b and b) = 3/8*2/7= 3/28
<u>Added up</u>
- 5/14 + 3/28 = 10/28 + 3/28 = 13/28
Probability of 2 same colored balls is 13/28
Answer:
New cars sold = 20,
Used cars sold = 25
Cars serviced = 290
Step-by-step explanation:
In a month they sold fifteen less used cars than twice the number of new cars.
Lets say 'x' number of new cars were sold, then:
The number of used car sold is:

In the same month they serviced fifty more than twelve times the number of new cars sold. So the number of cars serviced is:

Altogether they sold or serviced 335 cars, so the sum of all the cars sold and serviced should be 335:

Solving for 'x' we get:




Therefore, the number of new cars sold in that month is 20.
Number of used car sold 
Number of cars serviced 
We can also cross check by summing them up:

Answer:
80
Step-by-step explanation:
The ratio of sweets between the people would be
Sushil:Alex:Peter or 3:2:5
In this case, Sushil has 24 sweets meaning that 3 was multiplied by 8 in order to get 24. This means that we have to multiply all the numbers by 8 and and them up.
24+(2x8)+(5x8)
=24+16+40
=80 sweets
