The value of the probability P(3≤x<7) is 1
<h3>How to evaluate the probability expression?</h3>The expression is given as: P(3≤x<7)
This is calculated using:
P(3 ≤ x < 7) = P(3) + P(4) + P(5) + P(6)
Using the figure of the probability density function (see attachment), we have:
P(3 ≤ x < 7) = 0.30 + 0.30 + 0.20 + 0.20
Evaluate
P(3 ≤ x < 7) = 1
Hence, the value of the expression is 1

x = –6
Solution:
Given expression is .
Step 1: Isolate the radical by subtracting 5 from both sides of the equation.
Step 2: Cube both sides of the equation to remove the cube root.
Cube and cube root get canceled in left side of the equation.
Step 3: To solve for x.
Add 2 on both sides of the equation.
Hence the solution is x = –6.
