Answer:
P(AC∪B)=0.9+0.35=1.25
Step-by-step explanation:
I am not sure if A = {E1, E2} and others are combined probability, but try either way and see if it works or not. Are events combined or mutually exclusive?
1. Find P(Ac ∪ B)
Use probability formula (Mutually exclusive): P(A∪B)=P(A)+P(B)
2. Find P(A) and P(B) and P(C)
P(A) = 0.1 * 0.15 or try 0.1 + 0.15
P(A) = 0.0015 or 0.25
P(B) = 0.15 * 0.2 or try 0.15 + 0.2
P(B) = 0.03 or 0.35
P(C) = 0.1 * 0.25 * 0.3 or try 0.1 + 0.25 + 0.35
P(C) = 0.0075 or 0.65
P(AC) = 1.125*10^-5 or 0.9
3. Find answer
P(AC∪B)=P(AC)+P(B)
P(AC∪B)=1.125*10^-5+0.03=0.03
OR
P(AC∪B)=0.9+0.35=1.25
Ok so you would times 8.4*10 and get 84-6 which is 78, and 6.5*10 which is 65-6, so then you get 78+59=137 :)
Answer:
Divide a percent by 100 and remove the percent sign to convert from a percent to a decimal. The shortcut way to convert from a percentage to a decimal is by removing the percent sign and moving the decimal point 2 places to the left.
Step-by-step explanation:
5.25% = .0525

Solution: The regression equation is:
Where x is the number of years since it opened in 2003.
We have to find the cost of a vehicle to drive through the safari in 2008.
Therefore using the given equation, we have:
Therefore, the best estimate for the cost of a vehicle to drive through the safari in 2008 is $8.42.
Hence the option C.$8.42 is correct
