Answers:

  • A) 3/10
  • B) 7/10

=================================================

Step-by-step explanation:

15 people said they plan to work out of 50 total.

15/50 = 3/10 of his sample plans to work, which is the experimental probability of picking someone who plans to work.

---------------

50-15 = 35 people do not plan to work

35/50 = 7/10 is the experimental probability of picking someone who doesn't plan on working.

Or you could compute it like this 1 - 3/10 = 7/10 because there are only two options. Either the person plans to work or they don't.
