Probability Skills

Calculate the probability of rolling a 5 on a fair six-sided die.

• 1/5

• 1/4

• 1/3

• 1/6

Interpret the probability distribution of a normal distribution curve.

• The normal distribution curve represents a discrete probability distribution

• The normal distribution curve represents a continuous probability distribution of a random variable, symmetric around the mean, with probabilities defined by the mean and standard deviation.

• The mean and standard deviation have no impact on the shape of the normal distribution curve

• The normal distribution curve is always skewed to the right

Apply probability in a real-life scenario: What is the probability of drawing a red card from a standard deck of 52 cards?

• 0.25

• 0.5

• 1

• 0.75

Understand conditional probability: If you know that a student is in grade 10, what is the probability that they are studying mathematics?

• 0.3

• 0.9

• 0.5

• 0.7

Solve a probability problem: If the probability of rain tomorrow is 0.3 and the probability of having a picnic is 0.6, what is the probability of having a picnic if it doesn't rain?

• 0.4

• 0.75

• 0.2

• 0.8571
