Answer:
x+74
Step-by-step explanation:
Answer: Option A
P(B and V)=10%
Step-by-step explanation:
To solve this poroblema we use the formula of combinations:

Where n is the number of objects that can be chosen and you choose r from them.
There are 5 colors of shirts.
The number of shirts that can be made by combining 2 of the 5 possible colors is calculated as:



The number of shirts that can be made by combining 2 of the 2 possible colors (B) and (V) is calculated as:

Then the probability is:

Remember there are 3ft in a yard and 12in. in a foot.
To convert 5.5ft to yd, divide by 3.
To convert 2.5yd to ft, multiply by 3 to get 7.5ft.
To convert 7.5 ft to in, multiply by 12.
Just remember when converting to a larger quantity (yards, for example) to a small (feet, for example), you multiply, and from smaller quantity to larger, divide.
