Answer with Step-by-step explanation:
Contain Buy Do not contain Buy Total
Spam 48 12 60
Not Spam 4 36 40
P(it contains the word buy and it is spam)=48/100
P(It is spam)=60/100
Baye's theorem states that:
P(A given B)=P(A∩B)/P(B)
P( it contains the word buy, Given that an email is spam)
=P(it contains the word buy and it is spam)/P(It is spam)
= 0.48/0.60
=0.80
Hence, Correct option is:
A.] 0.80
Here is an example:
Find the MAD of 2,4,6,8 Step 1 : Find the mean of the data : (2+4+6+8) / 4 = 20/5 = 4 Step 2 : Find the distance between each data and mean. Distance between 2 and 5 is 3 Distance between 4 and 5 is 1 Distance between 6 and 5 is 1 Distance between 8 and 5 is 3
Step 3 : Add all the distances : 3+1+1+3 = 8
Step 4 : Divide it by the number of data : 8 / 4 = 2 2 is the average absolute deviation.
In the number 582, the 2 has a value of 2.
In the number 528, the 2 has a value of 20.
