What does it mean to not replace an item in probability?

Back

Not replacing an item means that once an item is drawn or selected, it is not put back into the pool for future selections, affecting the total number of items available.

Front

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

Back

For two independent events A and B, the probability of both occurring is P(A) * P(B).

Front

What is the formula for calculating the probability of an event?

Back

The probability of an event is calculated as P(Event) = Number of favorable outcomes / Total number of possible outcomes.

Front

What is the probability of drawing a red card from a standard deck of cards?

Back

There are 26 red cards in a standard deck of 52 cards, so P(red card) = 26/52 = 1/2.

Front

What is the probability of drawing two cards of the same color without replacement?

Back

P(same color) = P(first card color) * P(second card color | first card color).

Front

What is the probability of rolling an odd number on a standard six-sided die?

Back

There are 3 odd numbers (1, 3, 5) on a die, so P(odd) = 3/6 = 1/2.

Front

What is the probability of drawing an orange card from a set of colored cards?

Back

If there are 5 orange cards in a set of 30 cards, P(orange card) = 5/30 = 1/6.

Front

What is the probability of drawing a specific card from a deck?

Back

The probability of drawing a specific card (e.g., Ace of Spades) is 1/52.

Front

What is the probability of drawing two green cards without replacement?

Back

If there are 2 green cards in a deck of 30, P(green, then green) = (2/30) * (1/29) = 2/870.
