Giving a test to a group of students, the grades and gender are summarized below. round your answers to 4 decimal places.
a b c total
male 16 13 6 35
female 2 3 8 13
total 18 16 14 48
if one student is chosen at random:
1. find the probability that the student was female and got a "b".
2. find the probability that the student was male and got a "a".
3. find the probability that the student got a b.

1). 0.1667

2). 0.3333

3). 0.3333

Step-by-step explanation:

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

=

=

= 0.1667

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

=

=

=

= 0.3333

3). Probability that the student got a B =

=

=

= 0.3333

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^
