Heads and Green 1
Tails and Yellow 6
Tails and Red 7
Tails and Blue 2
Tails and Green 3
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 number of times the result would be tails and red out of 130 trials, we use the probability of the compound event "Tails and Red" occurring.

We can see from the table that the total number of occurrences of "Tails and Red" is 7.

Therefore, the probability of the compound event "Tails and Red" occurring in a single trial is 7/130.

To find the number of times this event would occur out of 130 trials, we can multiply the probability by the number of trials:

(7/130) * 130 = 7

So, the result would be tails and red 7 times out of 130 trials.
