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.
B at least 70% i had the same question before and that was correct
87% of 73 is about 63.51 and 73% of 87 is 60.59 so 87% of 73 is greater
Answer:
2143.6 ft³
Step-by-step explanation:
We use formula number 2 to get the volume. V=4\3πr³
4\3 x 3.14 x 8³ = 2143.573333
Rounded of to the nearest tenth = 2143.6 ft³
