S = { O, A, K}

Events ------------ Probabilities

Prefer orange ----- P(orange)= __ %

Prefer apple ------ P(apple)= __ %

Prefer kale -------- P(kale)= __ %



Part B

Answer 1

Part A

30

44

26

Part B

176

Explanation:

Total: 65+110+75 = 250

P(O) = 75/250 × 100 = 30%

P(A) = 110/250 × 100 = 44%

P(K) = 65/250 × 100 = 26%

Apple juice:

44% of 400

44/100 × 400

176
