Rodney flips a fair coin and chooses a letter tile A, E, I, O AND U. He performs this experiment 50 times to determine the experimental probability that heads is tossed and the letter A is chosen. Which of the following is most likely to be the experimental probability that Rodney determined?

Question

Rodney flips a fair coin and chooses a letter tile A, E, I, O AND U. He performs this experiment 50 times to determine the experimental probability that heads is tossed and the letter A is chosen. Which of the following is most likely to be the experimental probability that Rodney determined? 
A. 1/11 
B. 9/25 
C. 4/7 
D. 2/3 
I worked this out and I came up with 1/10 x 3/11 = 4/110 = 1/25 but this isn't an answer.

Steve · Answer

where did you come up with 3/11? tossing the coin and picking a letter are independent events, so the theoretical probability is just 1/2 * 1/5 = 1/10
