Since the spinner has 4 equal colors, each color has a probability of 1/4 of being landed on. Similarly, the coin has a probability of 1/2 of landing on tails.
To find the probability of the spinner landing on red and the coin landing on tails in a single spin, we multiply the probabilities together:
P(red and tails) = P(red) * P(tails) = 1/4 * 1/2 = 1/8
Given that the student spins the spinner 130 times, the expected number of times he will get red and tails is:
130 * 1/8 = 16.25
Since we cannot have a fractional number of spins, we round down to the nearest whole number, meaning the student will get red and tails 16 times out of 130 spins.
The spinner had an equal chance of landing on 4 colors , yellow red blue and green . If the student were to flip the coin and spin the spinner 130 times , how many will the result be tails and red
