Concept:
Probability \(P(E)\) is defined as:
\[
P(E) = \frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}
\]
A standard deck of 52 cards has 26 red cards (Hearts and Diamonds). Numbered cards in each suit range from 2 to 10.
Step 1: Identify the favorable outcomes.
Numbered cards greater than 6 are: 7, 8, 9, and 10.
In red suits (Hearts and Diamonds), these are:
• Hearts: 7, 8, 9, 10 (4 cards)
• Diamonds: 7, 8, 9, 10 (4 cards)
Total favorable cards = \(4 + 4 = 8\).
Step 2: Calculate the probability.
Total cards = 52.
\[
P = \frac{8}{52}
\]
Divide both numerator and denominator by 4:
\[
P = \frac{2}{13}
\]
