The three ways are substitution, elimination, and graphing
25 in of rain in 2 weeks.
there are 14 days in 2 weeks
25/14 = 1.785 in per day
1.785 x 31 = 55.335 in. of rain
55.335 in of rain is your answer
hope this helps
Answer:
1
Step-by-step explanation:
Probability is given by number of possible outcomes ÷ number of total outcomes
Assuming we stop rolling the six-sided die once our sum is 290 ( exceeds 285)
Number of possible outcomes = 75, number of total outcomes = 290
Probability (75 rolls are needed to get this sum) = 75/290 = 0.259
Probability (more than 75 rolls are needed to get this sum) = 1 - 0.259 = 0.741
Probability (at least 75 rolls are needed to get this sum) means that either 75 rolls or more than 75 rolls are needed to get this sum = 0.259 + 0.741 = 1
