A:
Answer: For the 1st question: the answer is 1/5 or b.For the 2nd question: the answer is 2/3 or d.For the 3rd question: the answer is 42.9%.For the 4th question: the answer is 22.4%.Step-by-step explanation:Question 1: We have 12 + 8 + 2 (22) socks in total. We know that the sock that we pick cannot be brown so 22 - 12 is 10. We have 2 blue socks, so we have a 2/10 or 1/5 chance of picking a blue sock.Question 2: We have 13 + 4 + 8 (25) photographs in total.We know that the photograph we pick cannot be a wedding photograph so 25 - 13 is 12. We have 8 holiday photographs, so we have a 8/12 or 2/3 chance of picking a holiday photograph.Question 3: There are 14 part-time jobs, and we need one that you do need experience for. There are 6 that need experience in the part-time section, so the provability is 6/14. 6/14 = 0.42857 = 42.857%, which is 42.9% when you round it to the nearest tenth.Question 4: The probability is 0.15/0.67 = 0.22388= 22.388%, which is 22.4% when rounded to the nearest tenth.
