丸をつけたところをなぜかけるのか教えてください

箱の中に数字がかかれた10枚のカードが入っていて, 3 が6枚, 1 が3枚が1枚 ある。この箱からカードを1枚取り出し、数字を調べ、箱にもどしてからもう一度取り出 し、2枚のカードの数字の合計の枚数だけ 100円硬貨がもらえるゲームがある。 1回のゲ ームで,受け取る金額の期待値を求めよ。 また,このゲームの参加料が1回450円のとき,このゲームに参加することは得といえる か。 解説 2枚のカードの数字の合計をX とすると, Xのとりうる値は X = 0 となるのは, 0 のカードが2回出る場合で,その確率は X = 1 となるのは、0と1のカードが出る場合で,その確率は X = 2 となるのは、 1のカードが2回出る場合で,その確率は X = 3 となるのは、0と3のカードが出る場合で、その確率は X = 4 となるのは、1と3のカードが出る場合で,その確率は X = 6 となるのは、3のカードが2回出る場合で,その確率は X= 0, 1, 2, 3, 4,6 = 10 10 100 2X × 10 3 10 3 6 10 100 3 = 9 10 100 xoxo 10 6 12 10 100 3 6 36 2× 10 10 100 36 10 10 100 よって,次のような表ができる。 X 0 1 2 3 4 6 計 6 9 12 36 36 確率 1 100 100 100 100 100 100 よって、受け取る金額の期待値は 0x 1 100 +100x- 6 100 + 200x - 9 100 12 36 36 +400x- +300x- +600x 100 |100 100 42000 =420 (円) 100 したがって, ゲームの参加料450円よりもらえる金額の期待値の方が少ないから, ゲームに参加することは得とはいえない。
