Answer:
11.14
Step-by-step explanation:
Mean = sum of numbers / total numbers
the mean of the 7 numbers = sum of the numbers / 7
sum of numbers for the 3 numbers = 10 x 3 = 30
Sum of numbers for the other 4 numbers = 12 x 4 = 48
Sum of the 7 numbers = 48 + 30 = 78
Mean of the 7 numbers = 78 / 7 = 11.14
Answer:
Step-by-step explanation:
Probability of getting the newspaper on his front porch = P(A) = 0.64
Probability of finding the newspaper on his lawn = P(B) =? (We don't know, this is what we have to find.)
Total probability = 1
Formula, P(A) + P(B) = 1
Let's put all values in this formula,
0.64 + P(B) = 1
P(B) = 1 - 0.64
P(B) = 0.36
Thus, the probablity that Mr. Johnson finds his newspaper on his lawn is 0.36 or 36%.
