An athletic director pays $90 for 12 sun visors for the
softball team. The rate per sun visor is equal to $90 / 12 sun visor = $ 7.5
per sun visor. So the athletic director should pay ($ 7.5 per sun visor)*(15
sun visor) = $ 112.5

It really depends on the situation as probability depends on logic more than simple mathematical equations. However you must keep in mind a few principles: 
1- P = number of possible outcomes of the event / total outcomes 
2- P always less than or equal to 1. 
3- For independent events A and B to occur simultaneously, P= P(A) x P(B) 
You can send me the question you’re stuck at for further help.
        
             
        
        
        
Answer:
21/32 square inches.
Step-by-step explanation:
The area of a rectangle = length x width
The area of her picture = length x widht
= 7/8 x 3/4
= 21/32
The area of her picture is 21/32 square inches.
Yes, I agree the area of the picture is 21/32 square inches.
The area must be in square inches. So she need to specify it.
Thank you.
