a student flipped a coin and spun a wheel 35 times. he landed on the comination of red and tails 7 times. if he repeated the action 130 times, how many times would he get red and tails
Given that the student landed on the combination of red and tails 7 times out of 35 spins, the probability of landing on red and tails is \( \frac{7}{35} = \frac{1}{5} \).
If the student repeated the action 130 times, we can calculate the expected number of red and tails spins by multiplying the probability by the total number of spins:
\( \frac{1}{5} \times 130 = \frac{130}{5} = 26 \)
Therefore, if the student repeated the action 130 times, he would expect to get the combination of red and tails 26 times.
