This problem is fairly simple if you know the exponential equation, you start with y=78(.17)^x. the you put 10=78(.17)^x, then you solve for x
10=78(.17)^x
-78
-68=.17^x
divide .17 then you have your answer!!
Answer:
C is the correct option
Step-by-step explanation:
To find the probability of P(a or b) we will use the formula:
P(a or b)= P(a)+ P(b) - P(a-b)
Now put the given values in the formula:
P(a or b)= 0.60+0.25-0.15
P(a or b)=0.85 - 0.15
P(a or b)= 0.70
Thus the correct option is C....
