A contractor is paving 1 mile 201.25 yards of a county road
Given distance is 1 mile and 201.25 yards
First we will convert 1 mile in feet.
1 mile = 5280 feet
Now we will convert 201.25 yards in feet
1 yard = 3 ft
201.25 yards =
feet
So total distance in feet is = 5280+603.75 = 5883.75 feet
1 foot = 12 inches
0.75 feet =
inches
This is 5883 feet and 9 inches.
Relationship B is represented by B. So C and D are both correct.
There are 4+6=10 people in the team.
First calculate in how many ways you can choose 3 people from a group of 10 people, using combination:

You can choose 3 people in 120 ways.
You can select 1 girl from a group of 4 girls in 4 ways.
Calculate in how many ways you can choose 2 boys from a group of 6 boys:

You can choose 2 boys in 15 ways.
Using the rule of product, you can calculate that you can choose 1 girl and 2 boys in 4×15=60 ways.
The probability of choosing 1 girl and 2 boys is the number of ways you can choose 1 girl and 2 boys divided by the number of ways you can choose 3 people from the group.

The probability is 1/2, or 50%.
0.0000079 is your answer, I believe.
