There are 10 tickets in the box, 3 of them are winning. find the probability that you take one ticket from the box and it will be winning ticket, then you take second ticket and it will be also winning ticket. taken ticket is not returned back to the box. hint: p(a and b.= p(a)×p(b)

24

Step-by-step explanation:

Let the number of pinto beans be x , that is the number of white beans will be x + 36 , which means the total number of beans in the jar will be x + x + 36 = 2x + 36

Total ratio = 5 + 2  = 7

To find the number of pinto beans ,it will be

ratio of pinto beans / Total ratio  X Total number of beans , that is

X (2x + 36) = x

multiplying through by 7 , we have

2(2x+36) = 7x

4x + 72 = 7x

collecting the like terms , we have

72 = 7x - 4x

72 = 3x

x = 24

Therefore there are 24 pinto beans in the jar
