If a student does not like sandwiches, what is the probability that student also does not like pies?
81.3%
26.0%
23.1%
18.8%

Answer 1

Answer:

18.8%

Step-by-step explanation:

For calculating this, focus on one part of the table :

• The row where students do not like sandwiches

There are 32 students who do not like sandwiches, and 6 of them do not like pies. Take this a proportion :

• P (does not like pies, do not like sandwiches) = 6/32
• P = 3/16
• P = 18.8%

Answer 2

Students who don't like sandwiches also don't like pie is the 2 nd box on 2 nd line

Probability

• P(E)=6/32
• P(E)=6/32×100=3/16×100=18.8%
