Question

Given the table:

x 4 5 6 7 8
p(x) 0.2 0.2 0.2 0.2 0.2
Find the value of P(x < 8). Round your answer to one decimal place.

Answer 1

The value of P(x < 8) is 0.8 when rounded to one decimal place.

Step-by-step explanation:

The value of P(x < 8) is calculated by finding the cumulative probability of all values less than 8. Given the table, p(x) represents the probability for each x value. To find P(x < 8), we sum up the probabilities for x values less than 8. So, P(x < 8) = P(x = 4) + P(x = 5) + P(x = 6) + P(x = 7)

P(x < 8) = 0.2 + 0.2 + 0.2 + 0.2 = 0.8

Rounding the answer to one decimal place, P(x < 8) = 0.8
