To find out how many times the result would be tails and red in 130 trials, we add up the occurrences of tails and red from the table:
Tails and Red = 7
So, in 130 trials, the result would be tails and red 7 times.
Compound Event Total Number of Occurrences
Heads and Yellow 9
Heads and Red 3
Heads and Blue 4
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 out the total occurrences of tails and red when flipping the coin and spinning the spinner 130 times, we can calculate the probability of getting tails and red (which is 7 out of a total of 32 occurrences) and then multiply it by 130.
Probability of getting tails and red = (Occurrences of tails and red) / (Total occurrences) = 7 / 32
Number of occurrences in 130 trials = (Probability of tails and red) x (Total number of trials) = (7 / 32) x 130 ≈ 28.4375
Therefore, in 130 trials, the result would be tails and red approximately 28 times.
Probability of getting tails and red = (Occurrences of tails and red) / (Total occurrences) = 7 / 32
Number of occurrences in 130 trials = (Probability of tails and red) x (Total number of trials) = (7 / 32) x 130 ≈ 28.4375
Therefore, in 130 trials, the result would be tails and red approximately 28 times.

I apologize for the error in my previous responses. Let's correct the calculation.
From the table, we know that the occurrence of "Tails and Red" is 7.
To find out how many times the result would be "Tails and Red" in 130 trials, we can set up a proportion:
7 occurrences is to total trials (130) as 1 occurrence is to unknown total trials x:
7/130 = 1/x
Cross multiply:
7x = 130
x = 130/7
x ≈ 18.57
Therefore, in 130 trials, the result would be "Tails and Red" approximately 19 times.
