By addition theorem of probability,
P(AUB) = P(A) + P(B) -P(A∩B)
or
P(A or B) = P(A) +P(B) - P(A and B)
P(A or B) = 0.7 + 0.4 - 0.3 = 0.8
Therefore, the probability that randomly selected person likes pizza or burger is 0.8

Taking all the Fs to the left you get:
5F+2F=35
7F=35
F=35/7=5

Answer:
√10 units / √5√2 units
Step-by-step explanation:
It is correct that the triangle is 45° , 45° and 90°
Given that,
height of triangle = √5
base of triangle = √5
To find,
hypotenuse of triangle
As it is a right angles triangle so
hypotenuse² = base² + height²
hypotenuse² = (√5)² +(√5)²
hypotenuse² = 2(√5)²
hypotenuse = √(2(√5)²)
hypotenuse = √5√2
So the length of the hypotenuse is √5√2
If you are wondering how to find the formula for 45 45 90 triangle hypotenuse, it is
<h2>a√2 </h2><h3>where a is length of base/height</h3><h3>As,</h3><h3>a² + b² = c² => a² + a² = c² so c = √(2a²) = a√2</h3><h3 />
