Đáp án B
Gọi A là biến cố “Cú sút đó không vào lưới”. Nếu cầu thủ sút vào vị trí 1 hoặc 2, xác suất để bóng không vào bằng 2 1 4 . 1 4 = 1 8 . Nếu cầu thủ sút cào vị trí 3 hoặc 4, xác suất để bóng không vào bằng 2 1 4 . 1 4 . 1 2 = 1 16 . Suy ra xác suất để bóng không vào bằng P A = 1 8 + 1 16 = 3 16 .

Gọi \(A_i\) là biến cố cầu thủ sút vào vị trí \(i\) và \(B_i\) là biến cố thủ môn bay người tới vị trí \(i\)
Do 4 vị trí như nhau nên \(P\left(A_i\right)=P\left(B_i\right)=\dfrac{1}{4}\) với mọi i từ 1 tới 4
Xác suất cầu thủ ko sút vào là:
\(P=P\left(A_1\right).P\left(B_1\right)+P\left(A_2\right).P\left(B_2\right)+\dfrac{1}{2}P\left(A_3\right).P\left(B_3\right)+\dfrac{1}{2}P\left(A_4\right).P\left(B_4\right)\)
\(=\dfrac{1}{4}.\dfrac{1}{4}+\dfrac{1}{4}.\dfrac{1}{4}+\dfrac{1}{2}.\dfrac{1}{4}.\dfrac{1}{4}+\dfrac{1}{2}\dfrac{1}{4}.\dfrac{1}{4}=\dfrac{3}{16}\)
