Julius needs to determine how much information needs to be given about an isosceles triangle to be able to draw an isosceles tri
Brrunno [24]

Answer:

Six cases are enough to construct more than one isosceles triangle

Step-by-step explanation:

An Isosceles triangle is a triangle in which at least two of it's sides are congruent.

If two of the three sides of a triangle are congruent, but the third side is of a different length, the triangle is isosceles.

If all three sides of the triangle are congruent, even though this is an equilateral triangle, it satisfies the condition of an isosceles, and it is ok to still it isosceles.

Julius might decide to split information for a better explanation, it doesn't matter the number of cases he has, but six cases should be enough to draw an isosceles triangle.

Answer:

4% probability that he will correctly predict the two teams to play in the championship just by guessing

Step-by-step explanation:

A probability is the number of desired outcomes, divided by the number of total outcomes.

League A:

5 teams, he will predict one to be champion. So

P(A) = \frac{1}{5}

League B:

5 teams, he will predict one to be champion. So

P(B) = \frac{1}{5}

What is the probability that he will correctly predict the two teams to play in the championship just by guessing

P(A \cap B) = P(A)*P(B) = \frac{1}{5}*\frac{1}{5} = \frac{1}{25} = 0.04

4% probability that he will correctly predict the two teams to play in the championship just by guessing
