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?
Based on the data given in the table, the probability of getting tails is 5/10 (50%) and the probability of landing on red on the spinner is 3/10 (30%).
Therefore, the probability of getting tails and red is 5/10 * 3/10 = 15/100 = 15%.
If the student were to repeat the experiment 130 times, the expected number of times the result would be tails and red is:
130 * 15% = 130 * 0.15 = 19.5
Since the number of trials must be a whole number, the student is expected to get tails and red around 19 or 20 times out of 130 trials.
