Using it's concept, it is found that there is a 0.875 = 87.5% probability that the player wins the match.
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
In this problem, these following outcomes result in the player winning the match:
- Wins the third set, with 0.5 probability.
- Loses the third set but wins the fourth, each with 0.5 probability.
- Loses the third and fourth sets but wins the fifth, each with 0.5 probability.
Hence, the probability that he wins the match is given as follows:
p = 0.5 + 0.5² + 0.5³ = 0.875.

Answer:
B. 
Step-by-step explanation:
Given:
The given triangle is an isosceles right angled triangle with the legs equal to 6 cm each and the hypotenuse is 'x' cm.
Applying Pythagoras theorem which states that the square of the hypotenuse is equal to the sum of the squares of the other two sides. Therefore,

Therefore, the length of the hypotenuse is
cm.
Hence, the option B is the correct one.
