2. The sales promoters at a shop observed that 30% of the customers who visit the shop will buy a pair of shoes. The probability that a customer who buys a pair of
shoes will buy a pair of socks is 0.6. However, the probability that a customer will
buy a pair of socks only is 0.2. Find the probability that a customer who visit the
shop will buy
a.
A pair of shoes and a pair of socks.

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
