Good luck! I hope I helped!
Hello!
You first find out how many objects there are in total
4 + 9 + 3 = 16
Then you find the probability of Liliana picking a orange
Since there are 4 oranges and 16 things to pick she has a 4/16 chance of getting an orange
Next you find the probability of Liliana picking a pear
There are 3 pears and 16 items to pick so she has a 3/16 chance
Then you add them together to find the chance of either happening
4/16 + 3/16 = 7/16
So she has a 7 out of 16 chance of getting an orange or a pear
The answer is 7/16
Hope this helps!
Some basic formulas involving triangles
\ a^2 = b^2 + c^2 - 2bc \textrm{ cos } \alphaa 2 =b 2+2 + c 2
−2bc cos α
\ b^2 = a^2 + c^2 - 2ac \textrm{ cos } \betab 2=
m_b^2 = \frac{1}{4}( 2a^2 + 2c^2 - b^2 )m b2 = 41(2a 2 + 2c 2-b 2)
b
Bisector formulas
\ \frac{a}{b} = \frac{m}{n} ba =nm
\ l^2 = ab - mnl 2=ab-mm
A = \frac{1}{2}a\cdot b = \frac{1}{2}c\cdot hA=
\ A = \sqrt{p(p - a)(p - b)(p - c)}A=
p(p−a)(p−b)(p−c)
\iits whatever A = prA=pr with r we denote the radius of the triangle inscribed circle
\ A = \frac{abc}{4R}A=
4R
abc
- R is the radius of the prescribed circle
\ A = \sqrt{p(p - a)(p - b)(p - c)}A=
p(p−a)(p−b)(p−c)
