Answer:

Step-by-step explanation:
Let
represent students playing basketball,
represent students playing baseball.
Then,
, 
Let
be the total number of students. So,
.
Now,


3 students play neither of the sport. So, students playing either of the two sports is given as:

∴ 
From the probability addition theorem,

Where,
is the probability that a student chosen randomly from the class plays both basketball and baseball.
Plug in all the values and solve for
. This gives,

Therefore, the probability that a student chosen randomly from the class plays both basketball and baseball is 
the height of the tree is 23 feet .
<u>Step-by-step explanation:</u>
Here we have , Tony is 5.75 feet tall. Late one afternoon, his shadow was 8 feet long. At the same time, the shadow of a nearby tree was 32 feet long. We need to find Find the height of the tree. Let's find out:
According to question , Tony is 5.75 feet tall. Late one afternoon, his shadow was 8 feet long . Let the angle made between Tony height and his shadow be x . Now , At the same time, the shadow of a nearby tree was 32 feet long. Since the tree is nearby so tree will subtend equal angle of x. Let height of tree be y , So
⇒ 
But , From tony scenario
⇒ 
Equating both we get :
⇒ 
⇒ 
⇒ 
Therefore , the height of the tree is 23 feet .
1.9 = 1 9/10 in simplest form
To find Jackson's height, you subtract 9 from 63 which gives you 54. 63-9=54
