A student has a spinner and a coin.The student is running an experiment for math class.These spinner had equal chance of landing on 4 colors.Yellow red blue-green, the student flipped a coin and spun the spinner.As a result that recorded in the table if the student were to flip a coin in the spinner a hundred and thirty times how many times would the result be tails and red
To determine how many times the result would be tails and red, we first need to find out the probability of getting tails and red.
The probability of getting tails when flipping a coin is 1/2.
The probability of landing on red when spinning the spinner is 1/4.
To find the probability of getting both events happening at the same time (tails and red), we need to multiply the probabilities:
P(tails and red) = P(tails) * P(red)
= 1/2 * 1/4
= 1/8
So, if the student were to flip the coin and spin the spinner 130 times, the expected number of times they would get tails and red would be:
130 * (1/8) = 16.25
Since the result cannot be a fraction, we would round this down to the nearest whole number. Therefore, the student would expect to get tails and red about 16 times out of 130 trials.
