Tails and Red 7 . If a student were to flip the coin and spin the spinner 130 times , how many times would the result be tails and red ?
Assuming the coin and spinner are fair and independent of each other, the probability of getting tails on the coin is 1/2 and the probability of landing on red on the spinner is 1/4.
To find the probability of both events occurring at the same time, you multiply the probabilities together: 1/2 * 1/4 = 1/8.
So out of 130 flips/spins, on average, we would expect to see tails and red occur 1/8 of the time.
Calculating this: 130 flips/spins * 1/8 = 16.25
Therefore, we can expect to see tails and red occur around 16 times out of the 130 flips/spins.
