In-Class Probability Introduction

Front

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

Back

P(rolling a 4) = 1/6

Front

What is the probability of selecting a brown M&M from a bowl containing 4 yellow, 6 orange, 3 green, 5 blue, and 2 brown M&Ms?

Back

P(selecting a brown M&M) = 1/10

Front

What is the probability of rolling a number less than 7 on a standard die?

Back

P(a number less than 7) = 1

Front

Define sample space in probability.

Back

Sample space is the set of all possible outcomes of a probability experiment.

Front

What is the sample space for flipping 3 coins?

Back

Sample space = {HHH, TTT, HTH, THT, TTH, HHT, HTT, THH}

Front

What is the total number of outcomes when rolling a die?

Back

Total outcomes = 6 (1, 2, 3, 4, 5, 6)

Front

If a bag contains 3 red, 2 blue, and 5 green marbles, what is the probability of drawing a blue marble?

Back

P(drawing a blue marble) = 2/10 = 1/5

Front

What is the formula for calculating probability?

Back

Probability (P) = Number of favorable outcomes / Total number of outcomes

Front

What is the probability of drawing a card that is a heart from a standard deck of 52 cards?

Back

P(drawing a heart) = 13/52 = 1/4

Front

What is an event in probability?

Back

An event is a specific outcome or a set of outcomes of a probability experiment.
