Out of 100 emails, 60 are spam and 48 of those contain the word buy. Of the remaining 40 emails that are not spam, only 4 emails
wel

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

His work should have looked like this.

2x + y = 5
x − 2y = 10

y = 5 − 2x
x − 2(5 − 2x) = 10
x − 10 + 4x = 10
5x − 10 = 10                  When he added in both sides, he subtracted 10 from 10,
5x = 20                      instead of adding 10 from 10 to make 20.
x = 4
2(4) + y = 5
8 + y = 5

y = -3
