nico uses a uniform probability model for an experiment using a deck of 40 cards. there are 10 blue cards, 10 red cards, 10 green cards, and 10 yellow cards in the deck. cards will be drawn one at a time and then replaced in the deck before another card is drawn. he uses the probability model to determine the probability of drawing a green card or a red card. what is p(green or red)? enter your answer as a simplified fraction in the box.

Answer

Explanation:

Step1: Identify favorable outcomes

Number of green cards = 10, number of red cards = 10. So total favorable outcomes = 10 + 10 = 20.

Step2: Identify total outcomes

Total number of cards in deck = 40.

Step3: Calculate probability

Probability formula is $P(A)=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$. So $P(\text{green or red})=\frac{20}{40}$.

Step4: Simplify fraction

$\frac{20}{40}=\frac{1}{2}$.

Answer:

$\frac{1}{2}$
