Question

Giving a test to a group of students, the grades and gender are summarized below. Round your answers to 4 decimal places.

Answer 1

Answer:

1). 0.1667

2). 0.3333

3). 0.3333

Step-by-step explanation:

1). Probability that the student was female and got a 'B'

= $\frac{\text{Number of female students who got B}}{\text{Total number of students}}$

= $\frac{3}{48}=\frac{1}{16}$

= 0.1667

2). Probability that the student was male and got an 'A'

= $\frac{\text{Number of male students who got A }}{\text{Total number of students}}$

= $\frac{16}{48}$

= $\frac{1}{3}$

= 0.3333

3). Probability that the student got a B = $\frac{\text{Number of students who got B}}{\text{Total number of students}}$

= $\frac{16}{48}$

= $\frac{1}{3}$

= 0.3333
