The probability of an event is a number that measures the likelihood that the event will occur. Probabilities are between and 0 and 1, including 0 and 1. Let the probability of an event. a. Write and graph a compound inequality that represents all possible probabilities

215.92 dollars is the answer

a. is correct

see explanation

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -

the answer is  

a.
