Answer:
The value of x = 10.
Step-by-step explanation:
From the given triangle,
We know that the sum of a triangle is 180°.
i.e.
K + L + M = 180°
(5x - 18)° + 90° + (3x + 28)° = 180°
Therefore, the value of x = 10
Probability helps us to know the chances of an event occurring. There are 8 outcomes.
<h3>What is Probability?</h3>Probability helps us to know the chances of an event occurring.
Let's suppose someone flips a fair coin three times.
1. The outcomes of the coins are,
Therefore, there are 8 outcomes.
2. The probability of getting exactly one tail is,
P(X=1) = 2/8 = 1/4
3. The probability of getting at most two tails is,
P(X≤2) = P(X=1) + P(X+2) = 1/4 + 1/2 = 3/4
