11 Q PROBABILITY PRACTICE

Front

What is probability?

Back

Probability is a measure of the likelihood that an event will occur, expressed as a number between 0 and 1.

Front

What is the probability of rolling a number greater than 2 on a standard die?

Back

The probability is 4/6 or 2/3, since the numbers greater than 2 are 3, 4, 5, and 6.

Front

What is the probability of spinning a yellow color on a spinner with equal sections?

Back

If the spinner has 6 equal sections and 1 is yellow, the probability is 1/6.

Front

How do you calculate the combined probability of two independent events?

Back

Multiply the probabilities of each event. For example, P(A and B) = P(A) * P(B).

Front

What is the probability of drawing a blue color and a number 4 from a set of colored numbers?

Back

The probability is 1/15, assuming there are 15 total outcomes.

Front

What is the probability of flipping a coin and getting tails?

Back

The probability is 1/2, as there are two possible outcomes: heads or tails.

Front

What is the probability of getting a vowel from the letters A, B, C, D, E?

Back

The probability is 2/5, since A and E are vowels out of 5 letters.

Front

What is the probability of rolling a number greater than 4 on a standard die?

Back

The probability is 2/6 or 1/3, since the numbers greater than 4 are 5 and 6.

Front

What is the probability of rolling an even number on a standard die?

Back

The probability is 3/6 or 1/2, since the even numbers are 2, 4, and 6.

Front

What is the probability of spinning green on a spinner with 8 equal sections?

Back

If 1 section is green, the probability is 1/8.
