In a group of 42 students, 9 study both Art and Biology.
LUCKY_DIMON [66]
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.

How do I Express the inequality x &lt; 7 using interval notation.
Sedaia [141]

Answer:  (-\infty, 7)

You can write this as (-infinity, 7) if you aren't able to use the infinity symbol.

====================================================

Explanation:

Think of x < 7 as writing -\infty < x < 7

So x is between negative infinity and 7, excluding both endpoints.

To write -\infty < x < 7 in interval notation, we write (-\infty, 7)

The curved parenthesis tell us to exclude the endpoint.
