Part A

We have to determine for which sport probability of being sold out is 0.4

Probability =

Let's determine the probability of being sold out for each of the sports

Probability (Rugby Sevens being sold out) =

⇒ Probability (Rugby Sevens being sold out) =

⇒ Probability (Rugby Sevens being sold out) = 0.6

Probability (Junior Athletics being sold out) =

⇒ Probability (Junior Athletics being sold out) =

⇒ Probability (Junior Athletics being sold out) = 0.6

Probability (Volleyball being sold out) =

⇒ Probability (Volleyball being sold out) =

⇒ Probability (Volleyball being sold out) = 0.4

Hence, for Volleyball the probability of being sold out is 0.4

Part B

Probability of both Rugby 7s and Junior Athletics being sold out = Probability of Rugby 7s being sold out × Probability of Junior Athletics being sold out

Substituting the individual probabilities from Part A in above equation

⇒ Probability of both Rugby 7s and Junior Athletics being sold out = ×

⇒ Probability of both Rugby 7s and Junior Athletics being sold out =

Hence, the probability of both Rugby 7s and Junior Athletics being sold out is

so then what are you asking?
