Answer:
The probability the student studies Art and
Biology is 0.2143.
Step-by-step explanation:
Denote the events as follows:
A = a students studies Art
B= a students studies Biology
The information provided is:
N = 42
n (An B) = 9
n (A' n B) = 10
n (A' n B') =7
Then the number of students who study Art
but not Biology is:
n(An B') = N -n (An B) -n (A' nB) - n (A'n B')
= 42 - 10 - 7 - 9
= 16
The number of students who study Art but
not Biology is 16.
Compute the probability the student studies
Art and Biology as follows:
P(ANB)
n(ANB)
= 0.2143
Thus, the probability the student studies Art
and Biology is 0.2143.
Each position in the sequence has 3 choices, and there are 5 positions, so we multiply 3 by itself 5 times:
Hello from MrBillDoesMath!
Answer:
-g (5 + 17f)
Discussion:
The terms only have the factor "g" in common so
-5g + ( -17fg) = => factor "g" from each term
g ( -5 - 17f) =
-g (5 + 17f)
is as much as it can be factored.
Thank you,
