Important Questions from Probability

1multiple correct

Which of the following are properties of probability? (Select all correct answers)

Show answer

Probability is always between 0 and 1, Sum of probabilities of all outcomes in sample space is 1, Probability of impossible event is 0, Probability of sure event is 1

Basic properties: 0 ≤ P(E) ≤ 1, P(impossible event) = 0, P(sure event) = 1, and sum of all probabilities = 1. Probability cannot be negative.

2multiple choice

A die is rolled. What is the probability of getting a number greater than 4?

Show answer

1/3

Numbers greater than 4: {5, 6}. Favorable outcomes = 2. Total outcomes = 6. P(number > 4) = 2/6 = 1/3

3multiple choice

Three coins are tossed. What is the probability of getting all heads?

Show answer

1/8

Sample space has 2³ = 8 outcomes. All heads = {HHH} = 1 outcome. P(all heads) = 1/8

4multiple choice

If P(E) = 0.4, what is P(not E)?

Show answer

0.6

For complementary events: P(E) + P(not E) = 1. Therefore, P(not E) = 1 - P(E) = 1 - 0.4 = 0.6
