A student has 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

Answer 1

The probability of getting tails on a coin flip is 1/2, and the probability of landing on red on the spinner is 1/4.

To find the probability of getting tails and red, you multiply the probabilities:
1/2 (for tails) x 1/4 (for red) = 1/8

Now, since the student is going to repeat the experiment 130 times, you can determine the expected number of times the result will be tails and red by multiplying the probability by the number of trials:
1/8 x 130 = 16.25

Since you can't have a fraction of a trial, you would expect to get tails and red 16 times in 130 trials.
