marco draws a card and replaces it 10 times from a standard deck of 52 cards. he draws 8 red cards and 2 black cards. what is the experimental probability of drawing a red card?\na $\frac{1}{2}$\nb $\frac{1}{4}$\nc $\frac{2}{3}$\nd $\frac{4}{5}$

Answer

Explanation:

Step1: Recall experimental - probability formula

Experimental probability (P(E)=\frac{\text{Number of times event E occurred}}{\text{Total number of trials}})

Step2: Identify values

The number of times a red - card was drawn is 8 (number of times event occurred), and the total number of trials is 10.

Step3: Calculate probability

(P(\text{red})=\frac{8}{10}=\frac{4}{5})

Answer:

D. (\frac{4}{5})
