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?
Responses:
22 times
11 times
35 times
26 times
The total number of occurrences for Tails and Red is 7.
So out of 130 times, the student can expect Tails and Red to occur 130 * (7/28) = 130 * (1/4) = 32.5 times
Since it cannot occur 0.5 times, we can round down to get 32 times.
Therefore, the answer is 32 times.
