(PLEASE HELP) A contractor has 10 lots for sale to build on. 4 lots are greater than two acres. 6 lots are less than two acres. What is the probability that the next two lots sold will be less than two acres?
1/3

3/5

9/25

5/9

Respuesta :

Probability that the first lot sold will be less than two acres = number of lots less than two acres / total number of lots = 6/10 = 3/5
 
Probability that the second lot sold will be less than two acres = remaining number of lots less than two acres / remaining total number of lots = 5/9

Required probability = 3/5 x 5/9 = 15/45 = 1/3
