Question

What is the probability that an emotional health index score is 80.7 or 82.7?

A) P(80.7
B) P(x>80.7 and x<82.7)

C) P(x=80.7 or x=82.7)

D) P(x≤80.7 or x≥82.7)

Answer 1

The probability that a Health Index Score is either 80.7 or 82.7 can be found by adding the individual probabilities of each score.

Step-by-step explanation:

The probability that a Health Index Score is 80.7 or 82.7 can be found using the formula:

P(x=80.7 or x=82.7) = P(x=80.7) + P(x=82.7)

Since the score can only be one value, we can add the probabilities of each score separately. If the scores are independent events, the probability of each individual score would be:

P(x=80.7) = 0.01

P(x=82.7) = 0.03

So, the probability that a Health Index Score is either 80.7 or 82.7 is:

P(x=80.7 or x=82.7) = 0.01 + 0.03 = 0.04
