A student had a spinner and a 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?

To find the probability of getting tails and red, we need to look at the "Tails and Red" row in the table, which states that the occurrence is 7.
So, out of 130 trials, the expected number of times the result would be tails and red is 130 * (7/36) = 25
Therefore, the correct answer is 26 times.
are u sure
I apologize for any errors in my calculations. Let's double-check:
The total number of occurrences for tails and red is 7.
If the student were to flip the coin and spin the spinner 130 times, the expected number of times the result would be tails and red is:
130 * (7/36) = 2535/36 ≈ 7.08
Therefore, the correct answer is actually 7 times, rounded to the nearest whole number.
