Answer

Explanation:

Step1: Identify relevant probabilities

We are given the probability distribution table for (x) (number of sleep - walkers). The probability of getting exactly 4 sleep - walkers, (P(x = 4)=0.021) and the probability of getting 5 sleep - walkers, (P(x = 5)=0.004).

Step2: Calculate probability of 4 or more

The probability of getting 4 or more sleep - walkers is (P(x\geq4)=P(x = 4)+P(x = 5)). Substitute the values: (P(x\geq4)=0.021 + 0.004). (P(x\geq4)=0.025)

Answer:

0.025
