Final answer:
Mrs. Gold, with a 2 out of 5 success rate for hitting fairways, can expect to land on approximately 7 fairways during an 18-hole game after applying her success rate of 0.4 to the total number of holes.
Step-by-step explanation:
To determine the expected number of fairways Mrs. Gold should land on during an 18-hole game, based on her having landed on 2 out of 5, we start by calculating her success rate. Mrs. Gold's success rate is 2 fairways out of 5 holes, which is a 0.4 probability (since 2/5 = 0.4).
Next, we apply this success rate to an 18-hole game. The math here involves multiplying the number of holes (18) by the probability of hitting the fairway (0.4).
Expected fairways hit = Number of holes × Success rate
Expected fairways hit = 18 × 0.4
Expected fairways hit = 7.2
Therefore, Mrs. Gold should expect to land on approximately 7 fairways during an 18-hole game.
