A student had a spinner and coin. The student was running an experiment for math class. The spinner had an equal chance of landing on 4 colors: yellow, red, blue, and green. The student flipped the coin and spun the spinner, and the results are recorded in the table
If the student were to flip the coin and spin the spinner 130 times, how many times would the result be tails and red?
A. 26 times
B. 35 times
C. 11 times
D. 22 times
To find out how many times the result would be tails and red, we need to add up the occurrences of "Tails and red" from the table:
Tails and red = 7
Therefore, if the student were to flip the coin and spin the spinner 130 times, the result would be tails and red 7 times, since the events are independent of each other.
Therefore, the answer is C, 11 times.
