Answer:

Step-by-step explanation:
Given: There are 2 classes of 25 students.
13 play basketball
11 play baseball.
4 play neither of sports.
Lets assume basketball as "a" and baseball as "b".
We know, probablity dependent formula; P(a∪b)= P(a)+P(b)-p(a∩b)
As given total number of student is 25
Now, subtituting the values in the formula.
⇒P(a∪b)= 
taking LCD as 25 to solve.
⇒P(a∪b)= 
∴ P(a∪b)= 
Hence, the probability that a student chosen randomly from the class plays both basketball and baseball is
.
Answer:437.5
Step-by-step explanation:3.5 times 250=875 divided by2 =437.5
Answer:
Step-by-step explanation:
by reading the graph that says one square is the size 1 we can see that PX starts at 0 on the x -axis, and ends at 7 on the x-axis (horizontal) so
PX = 7 units
Answer:
F
Step-by-step explanation:
F is the answer because in order to have a right triangle you have to have two of the same lengths and one length that is longer than the two that are the same.
Hope this helps!
