Question 7.
Distribute.
8(20 – r) = __________
8(20 – r)
= 8 × 20 – 8 × r
= 160 – 8r

Question 11.
What is the probability that the spinner will land on a sport that requires a bat or racket? Total number of sports = 6
Probability that a spinner will land on a sport that requires a bat is 1/6
Probability that a spinner will land on a sport that requires a racket is 1/6
P(A or B) = P(A) + P(B)
P(bat or racket) = 1/6 + 1/6 = 2/6 = 1/3

Question 12.
